Rihanna Flashes Some Serious Sideboob in a Barely-There Bikini

Take notes, all prospective sideboob flashers, because Rihanna just showed everyone how it's done! As it turns out, though, that's pretty much the only thing we would recommend taking notes on from this particular trip.



One of the "Diamonds" singer's friends posted a whole bunch of pics of the bikini-clad RiRi during their Labor Day vacay in the Mediterranean, which included some shots where the 26-year-old is smoking a mysterious-looking cigarette.





Rihanna's longtime friend Katy Perry recently called out her fellow pop star on her pot use during an interview, telling Elle Canada "we all know how much pot you smoke!" and wondering how she still manages to look so "fresh." Rihanna hasn't been too shy about her marijuana use, either...especially back when she had her own Instagram account.



When she wasn't smoking and soaking in the sun on the deck of the yacht, Rihanna rode around the hills on an ATV with her friends.



Fortunately, her ATV ride was not as eventful as Justin Bieber's recent joyride, although it definitely could have ended in disaster given that she was reportedly drinking beer while behind the wheel.



Looks like BadGalRiRi is living up to her title, whether she still has the Instagram name or not.
