From Access Hollywood: SALERNO, Italy – Mariah Carey stripped down to this itsy bitsy bikini as she caught some ocean rays off the coast of Europe. The singing superstar spent her vacation on Roberto Cavalli’s yacht in fact, which no doubt explains why she looks so fashion fabulous accentuating her suit with some serious bling and a pair of wrap-around shades. Though she looks all by her lonesome atop the multi-million dollar cruiser, Mimi was actually hanging with a group of pals. They even seemed to take cues from the fashion world, posing glamorously, photo shoot style for their personal pics before sipping fine wine and jumping off the boat for a dip in the sea. People, Star Tracks: After performing in Paris, Mariah Carey soaks up the view of the Mediterranean on designer Roberto Cavalli's yacht near Salerno, Italy, on Friday.
