Rihanna and Matt Kemp's Cabo vacation rolled on yesterday afternoon when the two set out for a cruise on a yacht. Rih's cutout bathing suit left little to the imagination when she cuddled into her boyfriend's neck 

— check out the photos to see what I mean. Rihanna showed Matt how it's done on a jet ski as well, which is something she's an expert at. The new couple has been having quite the time in Mexico, hitting up some popular clubs and getting playful with the cameras. 

 Rihanna, a Barbados native, is no stranger to tropical fun and this time she's sharing all her bikini loving with her new favorite MLB outfielder.
