On Monday, the "Descendants" actor, 51, and Keibler, 32, soaked up some sun during a yacht trip with a group of friends.
Keibler rocked an turquoise, ikat-printed jumpsuit for the ride, while Clooney looked equally ready for summer in white shoes, light-blue trousers and a matching blue button-down.
Prior to their romantic European getaway, Clooney has been keeping busy campaigning for President Barack Obama's reelection. In May, he hosted a massive fundraiser at his LA Home for POTUS, which raked in nearly USD 15 million.
