ABC has announced Supernanny's fourth season, which will continue to follow British nanny Jo Frost as she attempts to help American parents reign in their unruly children, will premiere with back-to-back one-hour episodes on Wednesday, January 2 beginning at 9PM ET/PT.

ABC ordered 13-episode fourth seasons of both Supernanny and Wife Swap last January for 2007-2008 midseason broadcast. Supernanny -- a British import that first premiered as a midseason replacement for ABC in January 2005 -- is executive produced by series creator Nick Powell as well as Craig Armstrong and Nick Emerson of Ricochet, a British independent television production company.

Wife Swap's fourth-season premiere on Wednesday, January 2 at 8PM ET/PT will serve as a lead-in for Supernanny's fourth-season premiere.

In addition, ABC revealed Dancing with the Stars' sixth season will premiere on Monday, March 17 at 8PM ET/PT with a 90-minute performance episode broadcast.  ABC will then air Dancing with the Stars' first sixth-season results show broadcast on March 25 in its regular Tuesdays at 9PM ET/PT time slot.

Similar to this fall's ABC Monday night schedule, Samantha Who? -- a half-hour Christina Applegate sitcom -- will air in the half-hour period between Dancing with the Stars' sixth season 90-minute performance episodes and The Bachelor's one-hour episodes.  The Bachelor's twelfth season is scheduled to debut on Monday, March 17 at 10PM ET/PT on ABC.

Oprah Winfrey's The Big Give -- a new reality competition series executive produced by The Amazing Race co-creators Bertram van Munster and Elise Doganieri for Winfrey's Harpo Productions that will follow 10 people who are given money and other resources before being challenged to find "dramatic and emotional" ways to spend it on others -- is scheduled to premiere on Sunday, March 2 at 9PM on ABC.
