15Jerk - Taylor Momsen

Taylor Momsen sang her way into many people's hearts as Cindy Lou in the film How The Grinch Stole Christmas. As she got older, she also appeared on the series Gossip Girl. But reports started circulating around the time of her exit from the show

of her terrible behavior.

Tim Gunn, in particular, ripped into Momsen following a guest spot on the series when talking to E! News,

"What a diva! She was pathetic, she couldn't remember her lines, and she didn't even have that many. I thought to myself "why are we all being held hostage by this brat?"'

Momsen ended up leaving the world of acting to pursue her music career.
