Disick, 32, and Bartoli, 25, were photographed sitting across from each other on a luxury yacht, and in the backseat of a car rental.
The father of three wore palm tree patterned shorts, a cheetah-print shirt, and a baseball cap. He also carried a can of beer. Bartoli, meanwhile, wore short denim shorts and a loose-fitted gray top.
A day earlier, Kourtney Kardashian's longtime partner and Bartoli got touchy-feely while eating with friends.
