"Brooke's agent and Dancing's producers are in talks about her competing on the show," a source close to the situation told RadarOnline.com. "No formal offer has been made yet, but Brooke is a huge fan of the show, and would probably agree to appear given the opportunity."
I believe Brooke's biggest claim to fame is being harassed and abused by Charlie Sheen. That would put her in the "even sillier than Bristol Palin" category. But, since last season was successful, I think anything could happen!
