Cruising the waters as she continues her posh European holiday, Rihanna once again showed off her fine bikini form while living it up off the coast of Portofino, Italy on Saturday (July 28). The 24-year-old Barbadian beauty rocked a skimpy two-piece swimsuit with a leopard print design as she hopped in the refreshing waters for a snorkeling session in the Mediterranean.

Upon wrapping up her underwater sightseeing expedition, RiRi climbed back aboard her boat while popping open a bottle of Jay-Z’s Ace of Spades Champagne to drink with her friends. Meanwhile, the “We Found Love” hitmaker continues to post Twitter tributes to her late grandmother, Dolly, as she most recently penned a message reading, “Shine bright like a diamond.” An accompanying link led to a notebook paper tweegram with a handwritten note adding, “YOU AND i… WE’RE BEAUTiFUL LiKE DiAMONDS iN THE SKY!”
