Heather: "Hope My Leg Stays On!"

Some might see Heather Mills' artificial leg as a drawback for "Dancing with the Stars," but Mills plans on using it as a weapon!

In an interview with "EXTRA" correspondent Terri Seymour, Mills says, "Hopefully my leg will stay on ... it's very unlikely [it will come off] though it'd be funny to knock one of the judges out!"

Heather, who lost her left leg in 1993 after an accident involving a police motorcycle, seems an odd choice for a dancing competition, but she's not worried, "I have no fear, I'm quite happy to be thrown around."

Between dance classes, Mills also is battling estranged hubby Paul McCartney in divorce court, with preliminary hearings starting today in London's High Court.
