Rihanna sure knows how to make a day interesting. Last night, Rihanna ended her Diamonds World Tour at the New Orleans Arena and by the looks of it, she had some time off to practice her twerk skills. Along with her girl friends, Bad Gal RiRi moved her booty to T-Pain’s latest banger ‘Up Down (Do This All Day)‘ and filmed it for our viewing pleasure. Watch a couple of videos below.
