Rihanna shows off her booty and some PDA in Cabo.  And by PDA I mean Private Display of Affection – they’re on a yacht in the middle of the water, the paparazzi are like pirates out there shooting pictures!!  Anyway, looks like Rihanna is moving on from the Chris Brown thing (it was almost a year ago!) and has found some happiness with Matt Kemp.  She’s livin’ her life, heeey ay ay… or however the song goes…
