Season seven of Dancing with the Stars premiered on September 22, 2008 as a part of ABC's fall 2008 line-up. Instead of 12 couples like previous seasons, this was the first season to showcase a lineup of 13 couples. This season also introduced four new dances: the hustle, the salsa, the jitterbug, and the west coast swing, as well as Team Dancing.  Tom Bergeron and Samantha Harris return as the show's hosts. Len Goodman, Bruno Tonioli, and Carrie Ann Inaba continue as the judges this season, with Michael Flatley having appeared temporarily as a guest judge for Len Goodman during week six.
