Stars that rejected "Dancing"

We know who said yes to "Dancing With the Stars." But do you know who turned ABC down?

According to a source involved with casting, the network approached Facebook creator Mark Zuckerberg to join the dance card for the show's 11th cycle but was unable to secure him. The network also lobbied unsuccessfully for Sylvester Stallone, political commentator Ann Coulter, former Secretary of State Condoleezza Rice, the real Erin Brockovich, billionaire Richard Branson, comic actor Tim Allen and former TV darling Suzanne Somers.

"We've approached a lot of people over the years," says executive producer Conrad Green. "People say no for a variety of reasons. Some people like the show but think they suck at dancing. It's a lot easier to say no than it is to say yes." 

Others who have turned down the show in the past: Reality star Kirstie Alley, "Community" star Joel McHale and "The Price Is Right" host Drew Carey.

Although lobbying for a spot on the roster has proved successful in the past, the casting source said those who push usually have little success.

"Melanie Griffith tries to get on every season," the source said... She a pretty big star, they must being turning her down becuase they don't know if she could stay sober. WAIT... that can't be it!! After all, the Hoff made the cut, right?!?!?!
