Last night, late night talk show legend David Letterman read off the title of Young Jeezy's forthcoming fourth album, Thug Motivation (TM) 103: Hustlerz Ambition, and introduced the Atlanta native to the studio and television audiences. Even though T.I. wasn't present to perform it with him, Jeezy still decided to rap out his J.U.S.T.I.C.E. League-produced single, "F.A.M.E.," with the help of a live backing band. The song is the current single off of TM 103, which will officially hit stores on December 20.
