This year’s roster of hoofers once again includes a number of singers: Donny Osmond, Mya, Macy Gray, Kelly Osbourne and Aaron Carter.

Also on board are Melissa Joan Hart, Debi Mazar, Ashley Hamilton, Joanna Krupa, Kathy Ireland, Mark Dacascos, Chuck Liddell, Louie Vito, Natalie Coughlin, Michael Irvin and Tom Delay.

Yup. That Tom Delay. The former Republican majority leader. To quote Artie Johnson, “Verrry inter-esting.”
