The older ladies have been showing the younguns how it's done in the nudity department this week! Hot on the heels of Kathy Griffin's uninhibited topless shots, we have former FriendCourteney Cox teaching a master class in MILFdom frolicking in the ocean. Courteney has been on vacation all week in St. Bart's, where she's been parading her fabulously fit (and newly available- she and husband of 11 years David Arquette separated in October) figure in bikini, but these pictures take things up a notch- or should we say a nip?
