Watch: Rihanna celebrates end of 'Diamonds' world tour with some serious twerking!

One unique way to celebrate the end of a grueling world tour is to twerk, twerk, twerk! And that Rihanna most certainly did!
Backstage at the New Orleans Arena last night, Rihanna brazenly showed off her twerking skills alongside BFF Melissa Forde! She moved her ass to T-Pain's 'Up Down (Do This All Day)'. Perhaps it would have had a bigger impact if there were more junk in that trunk but at least she has something to work with, unlike a certain Ms. Cyrus. Check it out!
