The sexy French vacay continues! Ashton Kutcher and Mila Kunis are still enjoying time on Princess Beatrice of York's stunning, multi-million dollar yacht in the south of France, while the rest of us watch with envy ...

So how did Ashton get so chummy with the royals, you might ask? Well, Princess Beatrice's boyfriend, Dave Clark, is head of astronaut relations for Virgin Galactic. Ashton was one of the first celebs to sign up to make the trip into outer space when the Richard Branson-owned enterprise "launches."

In the meantime, Ashton will keep is feet on terra firma ... unless you count the time he's got his top-siders firmly planted on the teak deck of a mega-yacht!
