Sam Worthington and Lara Bingle couldn't keep their hands off each other during a beach day in Capri, Italy, on Thursday. They took to the water for a refreshing dip before sprawling out on some rocks, and Sam, who showed off his shirtless body in a pair of trunks, laid a sweet smooch on Lara as she worked on her tan in a black bikini. The Aussie lovers apparently jetted to Italy earlier this week for the tropical getaway and seemed to be in a romantic mood as they relaxed together on the island. Sam and Lara have been dating since last year and showed equally hot PDA during a beach day in Australia back in October. Rumors have persisted that the two secretly tied the knot, since earlier this year when, during an NYC altercation between Sam and a photographer, the Avatar star referenced Lara as his "wife."
