When: 1/9/2010

Trina had a special guest in store for her fifth studio album, Amazin', but due to leaks, her Lady Gaga collaboration, “Let Them Hoes Fight,” hit the Internet months before its proper May release date. The song was written by Gaga, had her on the hook, and featured a short rap verse by the pop star at the end. No wonder the song came out prematurely—Gaga rapping doesn't happen often.
