Saw this on TV and was shocked ,even for Madonna standards this was very bitchy. It was MIA's mistake to take part on this kindergarden song from the beginning. It definitely hurt her independent alternative artist integrity. What did she get from it? Exposure to Bieber crowd she doesn't need at all and a Madonna chanting puppet role that's humiliating. Minaj on the othert hand is perfect for it. Plus now she's publicly called out by a woman who invented contraversial performances and attention seeking stunts. Come off your high horse Madonna, they should be chanting that.
