Are you ready for the list of celebrities vacationing together in Hawaii? There's Courteney Cox, David Arquette, and Coco; Tobey Maguire, Jennifer Meyer, and Ruby; Isla Fisher, Sacha Baron Cohen, and Olive; Leonardo DiCaprio, Lukas Haas, and a whole bunch more buddies. Phew. The A-List group of friends were all out on a boating, snorkeling, paddling trip together at the end of last week, and there's just too many treats to even describe in these photos. From Leo playing with little Olive to Isla not being quite as adept on the surfboard as Courteney and her hot bikini body. How goofy does Leo look? We got to see a little of the Cox-Arquettes solo in Hawaii as well as Isla, Sacha, and Olive playing around, but it's so much more fun to see the whole crew together! What a great way to celebrate the end of Summer.
