Vanessa Hudgens only had eyes for boyfriend Austin Butler on the carpet at last night's LA premiere of Journey 2: The Mysterious Island. They were joined at the event by her costars Josh Hutcherson, Dwayne "The Rock" Johnson, and a Monique Lhuillier-clad Kristin Davis at Grauman's Chinese Theater. Rachel McAdams doesn't have a role in the film, but her The Vow is coming out soon. She donned a gorgeous Peter Som dress and shirt for the occasion, and later attended the afterparty at The Colony nightclub to pose for pictures with High School Musical buds Ashley Tisdale and Vanessa. The screening was held a week before the movie arrives in theaters next Friday, Feb. 10. The cast has spent a great deal of time together recently. Vanessa, Josh, and the gang were just in Hawaii for a press junket — stay tuned for our chat with them! There were hours free from press duties, though, and Vanessa Hudgens slipped into a bikini for some beach fun with Austin.
