Heather Mills says her prosthetic leg won't fall off during any routines on Dancing with the Stars.

This raises an obvious question: What the heck is she doing on the show if viewers won't get to enjoy the hilarity of a flying limb?

We understand that Dancing With the Stars doesn't exactly sign up A-list celebrities to shake their assets on the floor - but couldn't producers find someone who is at least known for more than a famous divorce case?

Addressing the question of whether her prosthetic leg might come off while she's competing, Mills - who was struck by a police motorcycle in 1993, which necessitated the amputation of her left leg below the knee â€" tells TV's Extra:

"I'm quite happy to be thrown around and hopefully my leg will stay on."

She added: "It's very unlikely my leg is going to fly off, although it would be quite funny. I'll have a strap on, which I wouldn't normally in every day life."

Yeah, right. We're guessing Paul McCartney ended his marriage with this nut partly because a strap on was a major part of her everyday life.

With a laugh, Mills also says of dancing partner Jonathan Roberts: "I don't want to let Jonathan down or give anyone in the audience a heart attack."

Don't worry, Heather. No viewer will be watching you anyway. We'll all be looking at Shandi Finnessey.
