Courteney Cox Vacation with Josh Hopkins 'Strictly Platonic'

Courteney Cox and 6-year-old daughter Coco were seen Tuesday on the Caribbean sands with Cox's Cougar Town costar Josh Hopkins.
It's the latest sighting of Cox, 46, with Hopkins, 40, since her separation last October from husband David Arquette – they were spotted in Hawaii filming a scene in the pool and in the surf, but in those instances they were on location for the show.
This time, the getaway isn't work-related, but their rep tells PEOPLE romance is playing no role.
"The relationship is strictly platonic and they are away with a group of friends on vacation," the rep says.
According to a Cougar Town set source, "Courteney and Josh are great friends. There's definitely nothing going on there."
