Attending his manager Jason Barrett's wedding in Hawaii over the weekend, Zac Efron took his actress girlfriend Vanessa Hudgens for a romantic stroll on the beach on Sunday afternoon, October 26. The "High School Musical" sweethearts were photographed holding hands, hugging and snuggling.

Bare-chested Zac was spotted sporting a Calvin Klein underwear under his dark-colored shorts. Vanessa, meanwhile, wore a white dress and simply let her long, black, curly hair loose. She beautified her look with bracelets in both hands. A number of pictures, taken while Zac and Vanessa were enjoying their romantic beach stroll, are put all together in the video after the jump.

On Jason's wedding, held in the Aloha State, Zac and Vanessa showed off their on-screen dating skills in front of the other invited guests. "They were in such great spirits because of the wedding and because they heard early reports that HSM3 was turning out to have an amazing opening weekend," a source testified of the celebrity lovers and their movie "High School Musical 3: Senior Year."

Praising their dancing skills, the source continued saying, "They are the best dancers. They were totally getting down on the dance floor and having the best time."
