In case you were watching "House" or a very funny episode of "The Big Bang Theory," the replacement hoofers were announced Monday night on ABC's "Dancing With the Stars."

Holly Madison, the former member of "The Girls Next Door," and "Bachelor" reject Melissa Rycroft were trotted out to fill in for Nancy O'Dell and Jewel. Both O'Dell and Jewel were sidelined before the first dance because of injuries.

It was just a week ago that Rycroft was betrayed by "Bachelor" Jason Mesnick. Now Mesnick can watch as Rycroft spins around the floor with dance partner Tony Dovolan.

And Jewel's former partner, Dmitry Chaplin, is paired with Madison. Chaplin is 56 years younger than Madison's former partner, Hugh Hefner.
