"That Girl" was originally for Ne-Yo, who co-wrote it, but after Columbia Records dropped him, the song was given to Houston.

The song was his first single to chart on the Billboard Hot 100, peaking at number sixty-three in the US.

A music video for "That Girl" was shot in Los Angeles, California in February 2003.

It starts out with word "That Girl" then "starring Marques Houston".

The lead in the music video starring opposite Houston was long time principal dancer for B2K and IMx, Tanee McCall.
