Rihanna Had to Perform With Britney

You know how you were young and just about to go someplace really awesome, only to have your parents make you take your little brother or sister with you?
That has to be what it feels like to find out you�re performing with Britney Spears. So here�s Rihanna experiencing just that at last night�s Billboard Music Awards where Britney didn�t so much as �perform� as wander around and remember she�s supposed to do something with a stripper pole� eventually. Seriously, at one point, they just started having a pillow fight because apparently playing Pat-a-cake would�ve been way too complex, not to mention involve food. �Why you say cake but no have frostin�?� *throws Rihanna into audience*
