Making friends in Hollywood is considerably hard when you are rich and famous — you never know people’s real intentions as to why they want to be pals with you. But what happens when your new found friend interferes in your current relationship by making it known they are single and ready to mingle? Celebs have tried — and failed — to keep their secret friendship affairs under the radar, but one way or the other, they always get caught in the end, resulting in the loss of their partners and public scrutiny. Spending a considerable amount of time with people may sometimes lead to closer friendships, but there must always be a boundary which should never be crossed if one is seeing somebody else. The celebs that are gathered in this list were all in relationships when they decided to try and spice things up by hooking up with their friends. Some ended up choosing their best buds over their ex-lovers, while others had begged their exes for forgiveness, only to be shut down. The famous saying of, ‘You won’t know what you have until it’s gone,’ most certainly fits these ten celebrities who dared to cheat on their partners with close friends.
10 Simon Cowell and Lauren Silverman
Simon Cowell notoriously impregnated his best friend’s wife, having felt little remorse over his actions. The co-founder of The X Factor and America’s Got Talent, would vacation with his pal Andrew Silverman, all the time — and, as expected, Andrew’s wife, Lauren Silverman, would follow along. Simon was spending so much time with the couple that Lauren was more or less considered Simon's close friend, alongside Andrew. What her husband was not expecting to find out was that Simon and Lauren were allegedly sleeping with one another during their yacht vacations with Andrew. This yacht must have been extremely big for Andrew not to wonder why Simon and his wife were constantly missing.
9 Princess Diana
When Princess Diana’s marriage to Prince Charles started to fall apart, the two began cheating on one another, and it seemed like neither of them cared whether they would find out about it. After Charles was said to have gone back to Camilla, who he explained was the real love of his life, Diana was said to have had a string of affairs with close friends of her own. Barry Mannakee, James Hewitt, Will Carling, James Gilbey, Oliver Hoare, Hasnat Khan and Dodi al-Fayed, were all men that had been linked to Princess Diana following her heartache to Charles. Ironically, Diana reportedly felt she needed to mend her broken heart by moving on and finding someone new, having stressed that in her marriage to Charles, Camilla had openly invaded their romance. But how would Diana explain her affair with the men listed above (three of whom were married at the time)?
8 Heidi Klum and Martin Kristen
Following her separation from singer Seal in 2012, Heidi Klum did not waste any time moving on from her ex-husband, having admitted that she was seeing her bodyguard, Martin Kristen. According to several outlets, it was reported at the time of Heidi’s separation from Seal that the supermodel had been friends with Martin for some time before the two would go on to form a relationship with one another. Seal furiously lashed out at his ex-wife, telling reporters that he was convinced Heidi had been cheating on him with Martin before the couple had even separated. The singer would go on to retract his statement for the sake of the children he shares with the 42-year-old, yet it does not change the fact that Seal is convinced an affair was going on between the two during his marriage to Klum.
7 Arnold Schwarzenegger and Mildred Baena
Arnold Schwarzenegger and Maria Shriver had famously hired Mildred Baena to become their full-time maid, but the baggage that would come out of Baena's stay at the couple's home, would end up shocking Shriver to the core. Arnold, who had thought highly of Mildred, had a secret affair with her, which led to the birth of their love child, Joseph Schwarzenegger, born in 1997. Maria was stunned by the revelation, leading Shriver to separate herself from her husband of 29 years. It is unclear whether Maria is still hoping for a divorce from Arnold, but nonetheless, reports claimed she was heavily disgusted in Arnold's affair since Mildred had been considered a close family friend.
6 Ariana Grande and Justin Bieber
Ariana Grande had been locked in a 9-month relationship to rapper Big Sean, but that quickly fizzled when the singer would make flirty moves on Justin Bieber during her world tour. Grande had gotten considerably closer to the Biebs since the beginning of the year, and while Sean considers the Canadian star as a good friend of his, a line needs to be drawn when certain boundaries are crossed. During her performance of ‘Love Me Harder’ (ironic?), Ariana invited Bieber onstage, before embracing the 21-year-old with hugs and kisses on the cheek. According to outlets, Sean felt that the friendship between Justin and Sean had gotten too close, feeling that there was more to the story than they have led fans to believe. He dumped Ariana Grande a week later.
5 Benzino and Joseline Hernandez
Reality TV-star, Benzino, caused controversy when admitting he had allegedly slept with his friend’s wife, Joseline Hernandez. Benzino, who became close to the former stripper through Stevie J in 2012, confessed to having had an affair with her behind his back, causing an instant drift between their friendship. Stevie was very open when stating that he and Benzino have not been friends since his cheating revelation while his relationship to Joseline is supposedly ‘stronger than ever’.
4 Jude Law and Daisy Wright
During his relationship to Sienna Miller, Jude Law had gotten extremely close to the family’s nanny, Daisy Wright. The actor, who considered Sienna and himself as good friends to Wright, went on to have an affair with her behind Miller’s back; more shockingly, the affair was happening in public. The secret couple was able to hide their cheating affair rather well, seeing that photographers would never assume that the two were dating. Daisy was considered as the nanny and nothing more. So if she had been seen out and about with Jude Law, people would have just assumed that the two were doing something for the kids. Fortunately for Sienna, the actress eventually found out and ended her relationship to the 42-year-old.
3 Kim Kardashian and Kanye West
Kim Kardashian and Kanye West’s relationship has been building up since 2006 when they first met, it has long been reported. The 34-year-old reality star, who admits to having known Kanye for almost a decade before they became a couple, had told media outlets in the past that the rapper was nothing more than a friend, up until they began dating in 2011. But Amber Rose states otherwise. The ex-girlfriend to West had claimed that during her relationship to the Yeezus hit-maker, Kim would consistently phone her partner in hopes that they could meet up. Amber says she is certain that Kim, who claims to have only been Kanye’s friend, was hooking up with her man, which prompted her in dumping the 37-year-old for good.
2 Madonna and Alex Rodriguez
Madonna had formed a close friendship with Alex Rodriguez in 2008, back when the singer was still married to then-husband, Guy Ritchie. The ‘Girl Gone Wild’ hit-maker did not consider the friendship to be enough for her, having reportedly had a secret affair with Rodriguez that saw the two occasionally hook-up at Madonna’s New York apartment. It was claimed at the time that Madonna’s neighbors would constantly catch Alex leaving the pop star’s apartment, while Guy was busy working in London. Ouch.
1 Alicia Keys and Swizz Beatz
Alicia Keys and Swizz Beatz may have been happily married since 2010, but how the twosome got together is pretty interesting to say the least. The music mogul, who has produced hits for the likes of Nicki Minaj and Jay-Z, was married to songstress, Mashonda when he began working on Alicia’s music material. Alicia and Swizz became good friends, which then led to secret hook-ups behind Mashonda. Swizz's former wife would go on to call the singer a homewrecker for ending her marriage to the 36-year-old. While Mashona was taking care of the couple’s children, Swizz Beatz was reportedly spending more and more time with Alicia. The Harvard undergraduate student ended his romance to Mashonda in 2010, the same year he would go on to marry Alicia.
