Vanessa Hudgens showed off her bikini body in a black two-piece while hanging out on a yacht in Ischia, Italy, today. She was joined by a group of gal pals on the deck, as well as film directors Eli Roth and Terry Gilliam. She soaked up the sun while posing for photos and doing yoga moves with friends. Vanessa and Eli are in Italy for the Ischia Global Film & Music Festival, where their latest project, The Frozen Ground, is being shown this weekend. They attended a bash on the beach during the event Thursday night and were spotted dancing barefoot in the sand together. Vanessa has been traveling quite a bit to promote the crime thriller, which will be released Aug. 23. She hit the red carpet in a Jenny Packham jumpsuit for the film's London premiere earlier this week, and she also made a stop in NYC before heading abroad.
