WORST OUTFIT

Rapper M.I.A., who was due to give birth Grammy night, held her own during an all-boys' rap summit on Swagga Like Us with Jay-Z, Kanye West, Lil Wayne and T.I. But, oh, that outfit. She exposed her belly in a sheer black top that had a bikini cutout design, strategically covering her chest.

KANYE'S EGO MOMENT

West showed some sour grapes at not being recognized for being the greatest gift the music world has ever seen. He star and singer Estelle presented the award for Best New Artist, and West couldn't resist slamming Grammy for bestowing the honor to past winners John Legend and Amy Winehouse "but somehow, not to either one of us".
