Report: 'Dancing With the Stars' Champ Needs Surgery

Two-time winner of ABC's hit show "Dancing With the Stars" Julianne Hough has been diagnosed with endometriosis and will have to undergo surgery to have her appendix removed, People magazine is reporting.

“After consulting with her doctor, this was the course of treatment that was recommended,” says a statement on Hough’s web site.

The 20-year-old professional dancer and budding country singer, who has partnered with "Hannah Montana" actor Cody Linely on the show was rushed to Cedars-Sinai Medical Center following a live show on Oct. 21.

Hough’s rep said she “was experiencing slight stomach pains all day that increased and the doctors thought it was best to have them checked out,” People magazine reported.

Endometriosis is a painful medical condition that affects five to 10 percent of women, People said. It is the result of the development of uterine-lining tissue outside the uterus on the surfaces of organs in the pelvis or abdomen.

According to an inside source at DWTS, Hough's condition has meant she hasn't been able to rehearse properly with Linley.

"Julianne has been resting and taking it easy all week," said our source.
