Bachelor's Jilted Ex-Fiance to Join Dancing With the Stars

Well, that's one way to rebound.

Melissa Rycroft, who was famously dumped by fiancé Jason Mesnick in the most recent installment of "The Bachelor", will be next seen on "Dancing With the Stars".

A source tells People that Rycroft will be filling in for the spot left by Access Hollywood's Nancy O'Dell, who withdrew from the competition because of a knee injury.

Good thing Rycroft, a Dallas Cowboys Cheerleader, has some experience shimmying for the crowds. With the show's premiere on Monday, a production source says she only had four days to practice.

Watch the season premier of "Dancing With The Stars" at 9:00 pm (ET) tonight on ABC.
