"Legal or illegal, I do what it take." For 50 Cent, success will come, no matter the route he has to take--whether it goes through failed Columbia deals, unfathomable superstardom, independently-released G-Unit reunions or by hopping on a track with Elle Varner. That's just what Fif does here, calling back to his famous "In Da Club" ad-libs under the hook of Varner's "Birthday." He also drops two verses on the song, the first coming complete with an oblique reference to 50 Shades of Grey; at press time, XXL was unable to confirm whether the book was actually on the official G-Unit bookshelf. The song is taken from Varner's long-awaited sophomore LP, Four Letter Word.
