Catherine Zeta-Jones hit the deck of a yacht in her bikini off the coast of Italy today. She and shirtless Michael Douglas soaked up the sun and Catherine even got a massage as they continued their relaxing couple's getaway. The couple have been all over the Mediterranean enjoying time off, and Catherine and Michael even met up with fellow vacationers Jon Bon Jovi and his wife Dorothea. The foursome was spotted lunching at the beachside restaurant Club 55 and met up again later for dinner at Tetou in the South of France. Catherine's overseas stint comes after she filmed her part in Rock of Ages, which her costars Tom Cruise and Julianne Hough have been busy shooting in Miami. We already got our first look at Catherine Zeta-Jones in Rock of Ages, though the movie still had her much more covered up than she was during her bikini day.
