Washington, Mar 27 : Hugh Hefner’s ex-girlfriend Holly Madison has suffered a rib injury while rehearsing for U. S. reality TV series ‘Dancing With The Stars’.

But the ‘Girls Next Door’ star has vowed to continue competing on the show.

She was called up as a late replacement for singer Jewel, who was diagnosed with tendinitis after collapsing in rehearsals.

However, Madison has now suffered an injury of her own, after a fall left her with a painful rib injury.

"After experiencing pain in her rib area, Holly received medical attention. While she is not suffering from a broken rib, she does continue to feel a great deal of discomfort and was prescribed pain medication,” Contactmusic quoted a representative for the star as saying.

However, Madison is determined to dance on next week''s show.

"She is committed to the show and her partner, Dmitry, and will rest when she can. She fully hopes and, at this time, expects to dance on Monday,” said the rep.

Holly survived elimination with partner Dmitry Chaplin on the March 24 show. (ANI)
