They struck gold with their 2003 single, "Magic Stick," but by the time 2005 came around, there was no love lost between Kim and Fif. "I can't front," Kim said, "I don't have a lot of respect for 50 Cent because his music is hardcore...violent. And I love his music sometimes, but I feel like in his personal life, his real life, he carries that on, and that's not a great message, you know what I mean? I think he promotes it." The words promoted a brief beef that lasted until 2007 when the two paired up to record "Wanna Lick," a promo single for G-Unit's sophomore album, T.O.S.: Terminate on Sight.
