Reality show star Bethenney Frankel is trading in her Christian Louboutins for a pair of ice skates for ABC's Skating With The Stars.

Wearing a purple sparkly dress with white fishnet stockings, Ms. Frankel is ready to show the world just how nimble a 40-year-old can be. Yes, today, she turns the big 4-0!

This hot mama of one will be joining Motley Crue's Vince Neil, All My Children's Rebecca Budig and Olympic gold medalist Jonny Mosely on the ice.
