Former Playboy model Holly Madison will be making yet another costume change in Las Vegas.
The star of the newly-premiered “Peepshow” production at Planet Hollywood will serve as an honorary Octagon Girl at this Saturday’s UFC 100 event at the Mandalay Bay Events Center.
"UFC 100 marks the biggest event in the history of our company, so it's the perfect time to bring in the Ultimate Octagon Girl, Holly Madison,” UFC president Dana White said.
“Not only is Holly one of the world's most beautiful women, but she is a huge fan and supporter of the UFC, and we're looking forward to having her with us on July 11th."
Madison, who expressed interest in being an Octagon after attending UFC 98 in May, can be seen trying on the Octagon girls outfit in White’s most recent video blog.
The star of E! "Girls Next Door," and one-time flame of magician Chris Angel, joins current Octagon girls Arianny Celeste, Edith Labelle and Logan Stanton, as well as the soon-to-be-named winner of the first-ever UFC/Maxim magazine Octagon girl contest that will be named Saturday afternoon at the UFC Fan Expo.
