It's time for Paula Deen's dancing debut!

 Season 21 of Dancing With the Stars premieres tonight and although we're intrigued by all 13 mirror ball hopefuls, we've got a feeling that Deen has been cooking up some pretty sweet moves.

ET's Samantha Harris caught up with the chef and her pro-partner Louis Van Amstel at their Team Buttercup rehearsals, and we were surprised to learn that Deen has yet to whip up one of her favorite recipes for her leading man.

"The peanut butter pie in the cookbook, oh, I could eat it and I would never know [that it was low fat]," Deen spilled on the dessert from her healthiest cookbook yet, Paula Deen Cuts the Fat.

"So why haven't I had a piece of that?" Van Amstel asked with feign indigence.

"Because you won't let me quit dancing long enough to go into the kitchen!" Deen sweetly snapped.

Although Deen is still a powerhouse in the kitchen, the 68-year-old granny admitted that her memory is not what it used to be and she sometimes forgets her dance steps. Luckily, she and Van Amstel have perfected the art of talking through their smiles during the dances.

"Oh we're going to have a full conversation on that dance floor while we're smiling," she spilled. "[Louis will say,] 'Those boobs! Get those boobs up.' I said, 'They haven't been up in 40 years!'"

The overly candid cook was also open about her decision to join the dancing competition. "You know my family, my team, everybody was so excited. They said, 'Paula you've lost 40 pounds, you can do this, mama!'" she said.

Despite the fact that Deen has debuted a slimmer figure, don't expect to see her shimmying and shaking in those skimpy DWTS costumes!

"Oh no, not grandma, honey!" she laughed. "We don't want to make people sick the first night!"

Dancing With the Stars premieres tonight at 8 p.m. ET/PT on ABC.
