21-year-old Atlanta rapper B.o.B.'s debut album The Adventures of Bobby Ray delivered on the promise of its chart-topping single, "Nothin' On You," selling 84,000 copies to capture the No. 1 spot on the album chart this week, reports Billboard. And that's not all: Bobby Ray leads Billboard's Top R&B/Hip Hop Albums, Top Rap Albums, and Top Digital Albums charts as well. No doubt about it -- they got nothin' on you, Mr. B.o.B. Lady Antebellum's Need You Now sits in the No. 2 spot, Bullet for My Valentine achieved a career-high No. 3 with Fever, and Justin Bieber's My World 2.0 fell from No. 3 to the No. 4 slot. In addition to B.o.B.'s hit single, which features crooner Bruno Mars, Bobby Ray's success was aided by other high-profile collabos with T.I. (B.o.B. is signed to the rapper's Grand Hustle imprint), Weezer frontman Rivers Cuomo, Janelle Monae, Eminem, and Paramore's Hayley Williams.
