Actress Courteney Cox showed erected nipples when they popped out of her bikini and her ‘Cougar Town‘ co-star Josh Hopkins almost lost his shorts when they plunged into St Barts surf.

The former ‘Friends’ star looked stunning in a skimpy black bikini as she chilled on the beach with Josh and Coco, her six-year-old daughter with estranged husband David Arquette, reports the Daily Mail.

Meanwhile, a source close to the actress explained to US magazine: “It’s a group vacation. She’s close to her co-stars. She’s been like that since Friends. But there’s nothing more going on.”

Yesterday, the pair looked as if they were almost wearing matching beach outfits, with Courteney sporting a black and white floral print bikini and Josh wearing blue floral print shorts.
