Young Hollywood Hotties

JoBro mania has reached far beyond Disney's Camp Rock and Miley Cyrus' Best of Both Worlds tour. While the brothers have stayed true to their young fans, Kevin, Joe and Nick Jonas are impressing more than just tweens these days.

WHAT'S NEXT He and the Twilight cast have started filming the second installment of the series and his performance as Salvador Dali in Little Ashes is now in theatres.

After three installments as likable jock Troy Bolton in the now billion dollar High School Musical franchise, Zac Efron seems ready for the post HSM world.

This year, Radcliffe took on the male lead in Equus-a complete departure from anything Harry Potter related. Radcliffe was cast as a the dark character of Alan Strange in the Broadway show, who is put under psychiatric surveillance when he blinds six horses. It called for a 10-minute all-nude scene, received positive reviews from critics and left fans eager to see what Radcliffe will take on (or off!) after the seventh and final Potter film wraps.

While the cast has already started shooting the last film, the penultimate Harry Potter and the Half Blood Prince hits theatres July 17th.

Shia LeBeouf

has come a long way since he won an Emmy for his performance on Even Stevens just six years ago.

WHAT'S NEXT Labeouf's latest film Transformers: Revenge of the Fallen hits theatres June 24.

WHAT'S NEXT While Arrested Development is rumored to be made into a movie, he already has plenty to keep him busy with three movies coming out in 2009 including Year One, Youth in Revolt and Scott Pilgrim vs. the World.

After playing the despised Kevin Volchok-who ultimately killed Mischa Barton's character-on The OC, Cam Gigandet seems to have nailed the role of the desirable villain.
