Ashton Kutcher and Mila Kunis were spotted vacationing with Britain's Princess Beatrice of York and her boyfriend Dave Clarke in Saint Tropez, France, People magazine reported today.

The foursome spent time at Pampellone Beach and Le Palmiers club in Saint Tropez; they reportedly spent an evening on a yacht.

This is not the first time the two couples were spotted together - in May, they were seen in London visiting British nightclubs. But it does, apparently, mark the first time they decided to take their traveling adventures to continental Europe.

Kunis and Kutcher co-starred on Fox's "That 70s Show," which ended in 2006. They have been linked romantically since last summer.
