Rihanna goes for a quick snorkle in the Mediterranean

Rihanna recently went on a long Mediterranean cruise when she decided to snorkel with some of her gal pals.  One of her friends (not sure of her name) decided to get topless, Rihanna...she went in the water with a dress on.  Strange.  Her friends and her hit up the Christ Of The Abyss statue in San Fruttuoso Bay, near Portofino, Italy.

So what's up with Rihanna?  On stage she's not shy at all, but in the water, she wears a dress?  At least her friend had the stones to go out mostly natural!   Anyway, you're looking good in that last photo Rihanna!
