Rihanna took a late-night dip sporting a unique Bob Marley swimsuit in Barbados on Friday night. She spent the afternoon playing with friends, drinking beers, and popping on the back of a jet ski for a ride. Rihanna has been in her native country for the past week and has been living it up during her vacation. Rihanna wore a sexy white bikini for an afternoon by the ocean on Thursday, and she was in another skin-baring two-piece when she participated in the annual Kadooment Day parade.
