Scientology has got some serious secrets hidden in its closet. From what really goes on at those Sea Org meetings to the names of the A-list celebrities signing billion year commitments to the Church of Scientology. We know they’re out there, but as much as we love to peer into celebrities' lives, some of them just aren’t down with us knowing their religious business. And believe us, there’s a whole bunch of celebrities out there who really don’t want you to know they are into Scientology.

So just who are those all-important big names? Who’s donated vast sums to Scientology? Who’s been named in top secret Scientology documents and who’s being lined up to be Tom Cruise’s next wife?

We’ve got the answers to all of those questions and more. So if you’re dying to know who’s in, who’s out and why, we’ve pieced together the clues and found seven Hollywood stars who don’t want you to know they are into Scientology. And the eight who don’t care? You’ll probably be shocked by some of the big screen stars who are happy to be linked to the shadowy Hollywood cult hitting the headlines.

Laura Prepon

Laura Prepon really doesn’t care if the whole world knows she’s into Scientology. She even claims that Scientology is the REASON for her self-proclaimed ‘career-best’ performances. The Orange is the New Black star opened up to Scientology’s own ‘Celebrity Magazine’, saying: “I feel a lot of the auditing that I’ve had helps me to be willing to go there and be free and vulnerable and really jump into these scenes wholeheartedly.” But when you find out that auditing is a weird kind of counselling session in Scientology, that claim sounds a whole lot more crazy. Basically during the session you get hooked up to a lie detector while you share your deepest secrets. All of which the church keep on record. You know, for when you want to leave …

Keith Urban

You can kinda see why Keith Urban kept his Scientology links deeply hidden for so long. Rumoured to have been dabbling with the church’s beliefs for 20 YEARS, Urban started his Thetan quest when his career was stalling. Apparently if you complete enough Scientology courses you can acquire supernatural powers. But his wife Nicole Kidman, is unlikely to be impressed with this news. Her marriage to Tom Cruise was famously ruined by his obsession with Scientology and now it looks like her marriage to Keith is heading the same way. Still, imagine a world where Keith Urban and Tom Cruise have superpowers … Yeah, we’re not buying it either, but it would make a great movie.

Will Smith

Ever since Will first started to hang out with Tom Cruise, the celebrity rumour mill has had the Fresh Prince pegged as a Scientologist. And, for once, we think they might be on to something. Why? Well, Will’s handed over millions of dollars to the Church of Scientology. The money was used to build a school. And, although Will’s repeatedly denied any links with Scientology, it all seems kind of shady.

But that’s not the only thing that has Will labelled a secret Scientologist. There’s also After Earth to throw into the mix. The whole storyline is widely regarded to be based on Scientology beliefs. Coincidence much? We don’t think so. Come out of the cult closet already, Will.

Jada Pinkett-Smith

Jada’s been vehemently denying Scientology rumours alongside her husband Will Smith for years now. There’s just one problem. Former Scientology and all-round chatty-cathy, Leah Remini has outed her. Opening up to The Daily Beast, Remini said: I know Jada's in. She's been in Scientology a long time… I saw Jada at the Celebrity Centre.” But Jada doesn’t seem too keen on the world knowing she’s a Scientologist and took to Twitter to put the claims to bed. Tweeting up a storm she said: “I recently lit Shabbat candles with Rabbi Bentley at Temple Sinai... but I am not Jewish;

I have prayed in mosques all over the world... but I am not a Muslim;

Dianetics, and appreciate the merits of Study Tech… but I am not a Scientologist.” We’re not convinced.

Bart Simpson

Bart Simpson has been rallying support for Scientology events by calling people up in their homes and inviting them to learn more about the Church. Well, the voice behind Bart Simpson has, but still - those messages were left by Bart Simpson. Nancy Cartwright didn’t use her own voice. Which is just weird. If Bart Simpson called you up and invited you anywhere, you’re going to question it, right? Unless it’s to go to Flanders Leftorium because that would be kinda cool … Anyway, Nancy is definitely out and proud when it comes to Scientology. And the church must be stoked, Nancy donated $10m in 2007. Maybe they used it to open a Scientology Kwik-E-Mart?

David Beckham

Spend enough time with Tom Cruise and people are going to think you’re a Scientologist. Anyone linked to the Hollywood A-Lister immediately becomes the subject of scrutiny. And when you’re one of the most famous sports stars on the planet, it’s presumably difficult to keep your private life under wraps. David and Victoria Beckham have famously spent a lot of time with Cruise, though they were always quick to point out that Tom never tried to recruit them to Scientology. Though a secret source has a different take on things. They dished this dirt on the matter, saying: “Tom spoke to David for hours about Scientology. He feels it could help to lift him out of the blues over his football career. But Victoria is having none of it. She can’t see the point of joining something like that where you have to donate money.”

Jenna Elfman

You’ll have to go a long way to try and convince Jenna Elfman that Scientology is a shady cult-like religion. Whatever you’re selling, she ain’t buying. Though that doesn’t seem to stop many people trying to tell the Dharma & Greg star that Scientology is super cray. Here’s Elfman’s take on her religion of choice: “It's a new religion. Historically, every new religion has been [dismissed]. People were hanged, fed to the lions for their beliefs, so this is just a modern day evolution of what happens when something new comes into our culture.” Just one problem there, Jen. Scientology was literally created by a science fiction writer. Kinda like J.K. Rowling starting a religion about wizards. Actually, that’s one we might want to sign up to …

Chaka Khan

Let’s go ahead and give Chaka Khan a free pass here. Why? She might be shady about her actual religion, but she goes about it in the most pop star, diva-like fashion, we just can’t help but love her for it. The legendary singer apparently doesn’t dance to anybody else’s tune but her own. Here’s Chaka laying down some facts for us: “I belong to the religion of the Church of Chaka Khan, and I practice it every day. I live my religion, I consider it a personal thing. But I’ve taken some courses in Scientology, and they’ve been very, very helpful through life’s ups and downs.” Chaka, don’t ever stop being you. You big ol’ Scientologist, you!

Persia White

Remember Myspace? No, we don’t either … but Persia White is still battling on trying to use the outdated tech while the rest of us are tweeting up a storm. Though her Myspace profile has given us an interesting insight into her religious beliefs. Tucked away in the ‘heroes’ section of her page is none other than Scientology’s founder and all round crackpot, L. Ron Hubbard. Kinda like listing North Korea’s Kim Jong-Un in there … it reveals a certain something about a person, you know? That said, the Girlfriends star has never confirmed her links with the church. But secret Scientology documents revealed that she has taken courses with them. Maybe Persia belongs to the Church of Chaka Khan too. Or, more likely, the Church of Scientology.

Elisabeth Moss

This Scientology star is probably going to shock you - especially if you’ve been avoiding the celeb news for the past few months. Recently revealing her commitment to the Church of Scientology, Elisabeth Moss is only now starting to get chatty about her beliefs in interviews. The former Mad Men star has previously keeping her links to the secretive religion on the down low. But we wonder what could have sparked her new found pride in her Scientology status? Fun fact: Scientology leaders were once lining up Moss to be Tom Cruise’s next wife. Well, now we know where they got the inspiration for The Handmaid’s Tale.

John Travolta

What do Tom Cruise, Kirstie Alley and John Travolta all have in common? Well, so much tbh. Famous, intense, occasionally creepy and downright weird - all characteristics we could apply to the trio. But the star prize we’re looking for here is Scientology. Travolta’s one of their most famous members and, intriguingly, sources all over town suggest it could be for dark reasons. Apparently Travolta got pretty chatty during the Scientology auditing process, and now the sinister church has all of his darkest secrets. Which kinda makes you want to infiltrate Scientology and bust out some of those skeletons rumoured to be hanging about in Travolta’s closet.

Giovanni Ribisi

This Hollywood star was born into Scientology. Which seems pretty bleak - kind of like being born into the Kardashians, there’s just no escape. Despite his unfortunate start in life, Giovanni Ribisi is doing pretty well for himself. Possibly most famous for playing Phoebe Buffay’s brother Frank, in Friends, Ribisi also landed a few big screen roles. Now, starring in the breakout Amazon hit, Sneaky Pete, Ribisi is surrounded by Scientologists. His mum, Gay Ribisi - manages actors in Hollywood. His dad, Albert Anthony Ribisi, is a famous musician and his sisters, Marissa and Gina Ribisi are actresses. His sister Marissa is also married to a famous Scientologist, Beck.

Gloria Gaynor

If ever there was a women who you’d think would come out of the closet and admit something, it’s Gloria Gaynor. Her hit song ‘I Will Survive’ has been adopted as a gay anthem around the world so why then is she keeping quiet about her Scientology links? All the rumours are kind of left hanging. But when you’re still raking in the royalties from a song released in the 70s, it makes sense not to link yourself with a religion that labels gay people as deviants. Of course, Gloria Gaynor might be too busy living it up on her residual incomes to even care whether we think she’s tied to Scientology…

Anne Archer

Best known for her role in Fatal Attraction, Anne Archer is also an out and proud Scientologist, along with her husband John Archer. Members of the Church of Scientology since 1975, their son Tommy Davis became the head of the Church of Scientology's Celebrity Centre in LA. He’s stepped down from that role, with some suggesting that he’s headed to Australia to re-recruit a billionaire back to the religion. You see this is the problem with secretive, cult-like organisations. The crazy breeds the crazy rumours and no-one really knows what’s going on. All we can say is Anne’s firmly in the Scientology world and doesn’t care who knows it.

Tom Cruise

Can you really have a Scientology list without mentioning Tom Cruise? The celebrity face of the church, he’s seen in some Scientology circles as the ‘messiah’ of the religion. And that’s only scratching the surface of the downright crazy stories that leak from the Church of Scientology’s murky doorways. Apparently there are people in the church who’s sole existence is to surround Tom with Scientologists, just in case he hears some convincing arguments that lead him astray to buddhism. Scientology once auditioned wives for Tom - and gave Katie Holmes the dubious prize role. But however crazy the rumours get, you just need to look into Tom’s intense, crazy eyes when he talks about his beliefs to know he’s been reeled in, hook, line and sinker. Scientology caught themselves a big ol’ Hollywood fish and they ain’t never chucking this one back.
