Rihanna, ‘Diamonds’ Tour Rehearsal: Watch the Sexy Singer Dance

Speaking of concerts, Rihanna will be heading out on the road for her Diamonds world tour -- it kicks off this Friday (March 8) at the First Niagra Center in Buffalo, NY -- and is giving fans a sneak peak of what's going into the preparation.

Well, the choreography aspect, at least.

A behind-the-scenes video of the singer rehearsing made its way to her Youtube channel on Monday (March 4). During "Pour It Up," from Unapologetic, she bounces, sways and does some sort of twirl while otherwise showing off hip-hop-affected dance moves.

Step Up 3D, this is not. We assure you. But cool regardless.
