Robert Pattinson slipped from the top spot to number two in the 2011 PopSugar 100! After coming in at number one for 2009 and 2010, Robert still has an amazingly devoted fan base who come out to vote for him in droves, no matter the contest. Robert scored his first big post-Twilight success this year with Water For Elephants, which costarred Reese Witherspoon. Robert also got back into character as Edward Cullen to film bothBreaking Dawn movies, which come out in November of 2011 and 2012. Shooting the sexy honeymoon scenes gave us a peek at his hot shirtless body with a bikini-clad Kristen Stewart, and their offscreen romance is still hot as ever. He's currently working on another high-profile movie, David Cronenberg's Cosmopolis, which will once again cement Robert's leading man status after the franchise that made him famous.

4. Kristen Stewart

Kristen Stewart was eliminated early in a surprising 2010 PopSugar 100 turn, but in 2011 she shot right up to the top! The Twilight star has legions of devoted fans around the world, who love everything from her red-carpet style to her relationship with costar Robert Pattinson. Kristen celebrated a milestone birthday this year, turning 21 just as she finished up work on Breaking Dawn. Kristen landed on her first ever cover of Vogue and further cemented herself as a fashion risk-taker on red carpets while maintaining her t-shirt and jeans style otherwise. Kristen also shot On the Road and signed on to star in an upcoming adaptation of Snow White called Snow White and the Huntsman.

The sprightly Twilight star is best known for playing Bella's best friend and Edward's sister, Alice Cullen, in the vampire series, but Ashley is ready to break out into new roles this year. She costarred with Miley Cyrus as a rebellious teenager in LOL and shared the big screen with Jennifer Garner and Hugh Jackman in the political comedyButter. Her personal life often made headlines when she hooked up with Joe Jonas, but their fairy-tale romance ended after about six months. Ashley also landed a gig as the spokeswoman for Mark cosmetics and continues to be known for her commitment to fitness.
