Clearly these two are enjoying their vacation.
The romantic sighting comes just one day after the pair was spotted walking hand in hand as they hit the beach, which marked the first time the duo had stepped out together since news of Silverman's pregnancy was announced.
She and the X Factor judge are expecting their first child together.
Soon after Silverman reached a divorce settlement with her estranged husband, Andrew Silverman, a source told E! News that she and Cowell are "100 percent together," adding, "They are definitely a couple. The relationship is loving and they're very happy together."
