Heather Mills: Ready to Razzle Dazzle the 'Dance' Floor

She's been hounded and hunted by the British press ever since news broke of her impending divorce from Sir Paul McCartney.

But now Heather Mills is taking the paparazzi head on, as she sat down with “Extra's” Terri Seymour in this “Extra” exclusive at the Hotel Du Vin in England and opened up about her daring decision to join the new season of America's “Dancing with the Stars.”

“In my mad, crazy life, it's actually going to be great fun,” Mills admitted.

In fact, Heather's decision to hit the dance floor all started with a tabloid story.

“The tabloids had written that Heather's doing 'Dancing with the Stars,' and I wasn't,” she dished. “And they contacted me and said, 'Do you want to do it?' I said, 'Yeah, great. If it's helping a charity, great.'”

Mills, who lost a leg after being struck by a motorcycle, will be “Dancing” for causes close to her heart: children who need artificial limbs.

Because she has never had any formal dance training and she'll be doing it all on an artificial limb, Heather has to learn how to dance… and fast!

“I have no fear; I'm quite happy to be thrown around and hopefully my leg will stay on,” Heather joked. “It's very, very unlikely my leg's going to fly off, even though it'd be funny to knock one of the judges out.”

As for those sexy salsa costumes and revealing midriff dresses, Heather told “Extra,” “Now I'm hitting 40, so I think I'll keep my tummy covered.”

Heather has just three weeks to get ready to rumba, and she admitted she's been practicing at home with her 3-year-old daughter Beatrice, who Heather says “loves to do her little pirouettes.”

“I'm trying to practice going down the supermarket aisle, looking like a crazy woman,” Heather admitted.

With the camera craze following her every move, “Dancing” has thrust Mills even further into the spotlight; a photo was snapped just this week of her heading into a dance rehearsal with her spare legs in her bag.

“We're trying to work out which one is going to work for which heel height because what people don't realize is when you have a leg made it is only made for specific heel height,” Heather explained. “You can't go from high heel leg and put your trainers on, you've got to swap your legs.”

When Heather does take that brave step onto the “Dancing with the Stars” stage come March, she admitted she doesn't care if she wins or loses.

“I'm hoping that people will see you really can do anything you set your mind to,” she said.
