T.I.

Prolific Atlanta hip-hopper, reality-TV star and actor T.I. works a laid-back, Southern-steeped style of rap that's by and large wildly self-aggrandizing, but on occasion—as on "Sorry," his track with Andre 3000—exposes a chink in his 24-karat armor. Having collaborated with everyone from Eminem, Jay-Z and Rihanna to Justin Timberlake, Kanye and Cee Lo, the 35-year-old is also one of the best-connected MCs in the game. At tonight's show, cross your fingers for a sneak peek of forthcoming album The Dime Trap.
