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.

The single version, which can be found on the UK and Japanese pressings of the JoJo album, features Bow Wow.

In 2005, actress Alyson Stoner recorded a cover of "Baby It's You".

The video was directed by Erik White on location at Six Flags Magic Mountain and Hurricane Harbor.

Most of the performance shots were filmed in front of the Center Ring gaming area and other shots feature the ProSlide Tornado, Scream and Colossus roller coasters.
