The unlikely pair of preacher Ted Haggard and actor Gary Busey will be swapping their better halves for the sake of reality TV fun.

An upcoming airing of 'Celebrity Wife Swap' will feature Haggard, who stepped down from his position as president of the National Association of Evangelicals in 2007 after admitting to doing drugs and having a relationship with male prostitute, and Busey, who's extreme eccentricities have been highlighted in multiple reality television appearances.

The episode is being filmed Thursday at the GLBT Pride Center in Colorado Springs. It's unclear when the episode will air.

Haggard appeared with his wife Gayle in a 2009 episode of 'Divorce Court,' although the couple remains married. Busey married his second wife, actress Steffanie Sampson in May 2010.
