It looks as though Cameron Diaz got the better end of the deal when she "swapped" boyfriends with Jennifer Aniston. While Aniston's failed relationship with John Mayer, who had previously been seeing Diaz, has been all over the news, Diaz has been spotted having a blast with Aniston's former flame Paul Sculfor, according to Page Six. In fact, Diaz was said to be "wearing a chunky ring on her left ring finger."
