<P> The show 's theme song `` Living One on One '' , was written and performed by Shanice ( wife of the series star Flex Alexander ) and Tonex with music composed by Jonathan Wolff and Becky Kneubuhl ( who composed the scene - change music for the first season ) . The theme song was slightly shortened and remixed by Detail and Ray J for the show 's fifth season . A truncated version of the theme stripped of all lyrics except the words `` One on One '' , was used as a closing theme , heard only in syndicated airings . </P>
