What a good sport Shania Twain is! The singer is turning an embarrassing tumble into money for charity by auctioning off the high heels she was wearing at the CMT Awards in June. Twain memorably fell to her hip while walking to the presentation stage, but recovered gracefully.

Current bidding is at $500 for the size six, autographed BCBG Max Azria high heels. They're black satin with with a leather sole, and autographed on the inside of each shoe's strap. A tassel is missing from the left heel. Proceeds go to her Shania Kids Can charity, which provides food and support to underprivileged kids in Canada through the school systems.

After the slip, Twain joked that she's proud she's able to perform all of her own stunts. In a video to fans, she mentioned the idea of auctioning the heels off for charity.  "I never want to see those shoes again," she says. Competition for the footwear seems to be steep; 45 bids have already been placed for the auction, which began Monday and wraps on August 22.

Twain appeared during Sunday night's 'CMA Music Festival' special on ABC, but did not perform. Viewers got a look at what she'd been up to the last few years and the singer admitted to forcing herself to do some uncomfortable things. Falling on national television was likely not what she was referring to.
