Mimi in Bikini

"Glitter" "star" Mariah Carey was spotted chillin' on designer Roberto Cavalli's yacht in Salerno, Italy on Friday, seen here with a Penelope Cruz wannabe. Bellisima!

The better-toned and bronzed songstress also served as the yacht's photographer -- taking snapshots of her friends all over the boat. Float like a butterfly!

Mariah enjoyed a beverage before going for a quick dip and hopping on a jet ski.
