Songfacts®:

• This features Akon, who originated this track. Nelly told The Sun September 12, 2008 that getting the Sengalese rapper on board was tricky. He explained: "He's busy. He has his own record coming soon but then he played the track, cranked it up, and two days later called me and said, 'You got me. I'm in.'"
• This also features Ashanti and the song plays on Nelly's past relationship with the R&B singer.
• A different version was also released on Ashanti's album The Declaration, where the R&B singer has two verses rather than the single one on this recording. On both versions Akon sings the chorus.
• Akon originally wrote this in 2006 for Lil' Fizz, a former member of the boy band B2K. Once it was decided that Lil' Fizz would not be releasing an album, Akon took the song back and gave it to Nelly and Ashanti to develop.
• Nelly recalled to XXL magazine how he changed his mind about this song: "[Akon] sent it to me and it didn't hit me like right away. I burned the CD and I took it home in the car and my system I don't know but for some reason my system in my car is where I like to judge my music or something. Because I get a better feel even though it's louder in the studio or some s--t. But once I got in the car on my way home that s--t got the knocking I called that muthaf--ka right back like, 'Yo, you in line, cuz!' We did the joint and then I thought it would be hot to do it in kind of a collaboration or so to speak with Ashanti and she came [laughs]."
