He and Mila Kunis are currently on holiday with Princess Beatrice and Dave Clark in St Tropez.
But despite the illustrious company, Ashton Kutcher clearly only had eyes for his girlfriend.
The
35-year-old was seen leaning in and planting a kiss on the actress, 29,
as the pair walked hand-in-hand following a boat ride with the royal
and her friends in the French Riviera town.
Sneaking one in: Ashton Kutcher was seen
planting a kiss on girlfriend Mila Kunis' lips after a boat ride with
Princess Beatrice and Dave Clark in St. Tropez on Sunday.
The actor, often seen in a hoodie and jeans, dressed for the occasion in trousers, an orange shirt, jacket and a white sunhat.
Mila,
meanwhile, was more casual in skinny jeans, a navy sweater bearing a
picture of a giraffe and flip flops, which she carried as she walked
barefoot.
She wore her brown hair in a schoolgirl ponytail and shielded her eyes with brown aviator shades.
Keeping it casual: Mila opted for jeans, a
giraffe sweater and flip flops while Ashton dressed to the nines in
smart jacket and white sunhat as they walked hand-in-hand after their
boat ride
Unlikely friends: The Hollywood couple have
jetted into France from the UK to join Princess Beatrice and Dave Clark
on their holiday in St. Tropez
Celeb-watchers were stunned last month when the Hollywood couple started hanging out with Princess Beatrice and her boyfriend.
However,
it looks as if the unlikely friends have stepped their acquaintance up a
gear after the royal and her boyfriend invited the actors to join them
on holiday.
With
Mila having the weekend off filming Jupiter Ascending, they jetted from
London to Nice to join Beatrice and Dave in nearby St Tropez.
Soaking up the sun: Princess Beatrice was seen looking out at sea wearing a blue plaid shirt and brown sunglasses
Natural beauty: Mila wore her brown hair in a ponytail and shielded her eyes with large sunglasses
The two couples have been
spending lots of time together in recent weeks since Ashton joined Mila
in the capital, where she has been based since April while she films
Jupiter Ascending.
Ashton
met Dave last year after the actor bought a space flight on Virgin
Galactic, where Beatrice's boyfriend works in astronaut relations.
A
source told Heat magazine: 'Ever since Ashton was chosen to become the
500th space traveller on the Virgin Galactic last year, he’s become
friends with Dave, who is head of astronaut relations.
'It
isn’t just a superficial friendship, they get on really well, as Dave
introduced Bea to Ashton and Ashton introduced Mila to them.
'Mila
is impressed with the royal family, respects their tradition and
watched every minute of Kate and Wills’ wedding, so being friends with
Beatrice is a total head-trip.'
