Nancy Grace's Strategy To Win 'Dancing With The Stars'

Nancy Grace might be the most surprising star to join season thirteen's cast of "Dancing With The Stars," but don't think for one second that she isn't in it to win it.

"I'm the oldest and the fattest and I can't dance. Oops," Grace tells me. But she does have a strategy for winning -- making sure everyone is too scared not to vote for her. "I pray!" Nancy said chuckling.

Grace, whose HLN show beat out all of her ratings competition during the Casey Anthonyt trial, might come across as one tough cookie who is all about swift justice; however, off-camera Grace is known as a jokester who is adored by fellow talent on her network.

"I remember being in Orlando with Nancy when she waved a steak in the face of vegan, Jane Velez-Mitchell, and she turned white," an insider tells me. "But that's Nancy ... always the first to make a joke."

We can't wait to see Grace debut some choreographed moves and maybe a few pranks when "Dancing with the Stars" premiers on Sept. 19.
