T.I. is SERIOUS about being sorry. You know how I know? Because he put Mary J. Blige in his new video, "Remember Me," and no one calls on Mary J. Blige unless they're super serious. I'm not saying Mary J.'s a downer, but she is strictly business. No one puts Mary J. in their video strictly for comic relief, you know? She doesn't pop up in wacky pie-in-the-face gag reels. Because Mary J. Blige a closer.

But just because T.I.'s had the book thrown at him and the jail cell closed on him -- he's currently serving a 366-day jail sentence for attempting to buy firearms from an undercover cop -- doesn't mean he's gone for good. T.I. DOES NOT want you to forget him. Ever.

Promise T.I. you'll be waiting for him the minute he gets out of the clink by watching his new video, "Remember Me," directed by Jessy Terrero (50 Cent, Wisin & Yandel).

Maybe not that sorry?
