Written by Harvey Mason, Jr., Damon Thomas, Eric Dawkins and Antonio Dixon, and produced by The Underdogs, the song was released in September 2004 as the second single from JoJo's self-titled debut album. It reached number 22 on the Billboard Hot 100 and number eight on the UK Singles Chart. JoJo performed the song on All That in 2005.
