The Daily Grind Video

Rihanna is just full of surprises – and we love it. Little Miss Sunshine got extra wild on a party bus during a break from her Diamonds World Tour, even giving us her rendition of the uber-popular dance craze the Harlem Shake.

With a drank in her hand, and joined by her bestie Melissa and hairstylist, Yusef, our favorite good girl gone bad showed us that twerkin’ isn’t the only dance she’s doing these days.

Between the recent launch of her successful MAC collection, the release of her “Pour it Up” video and snagging four American Music Award nominations, the Bajan-beauty has a lot to celebrate.

Or maybe….Rihanna needed a break after getting her brand new Maori chisel and hammer tattoo. Whatever the reason, we love seeing RiRi bust a move.
