T-PAIN
At 22, Florida-born rapper T-Pain has already notched a nearly ridiculous string of chart hits, many of them collaborations with industry heavyweights like R. Kelly (''I'm a Flirt''), Chris Brown (''Kiss Kiss''), and Kanye West (''Good Life''). He's also had a few famous guests of his own: See this year's smashes ''Buy You a Drank (Shawty Snapping),'' featuring Yung Joc, and ''Bartender,'' with crooner Akon. Altogether, they've earned him four Grammy nominations: A Best R&B Performance nod for ''Bartender,'' a Best Rap Song one for ''Good Life,'' and two (!) in the Best Rap/Sung Collaboration category, for ''Kiss Kiss'' and ''Good Life.''
