The former Brady Bunch star will make her DWTS debut on Monday with pro partner Artem Chigvintsev. While she's not naturally drawn to dancing, she's bravely facing the competition at the insistence of her former TV mom, DWTS alum Florence Henderson.
"She was like, 'Mo, you have to do Dancing With the Stars,'" McCormick explained.
And apparently mom knows best, because she's having a ball! Plus, the iconic actress, who just turned 60 last month, is feeling better than ever thanks to a change in diet.
"I've had weight issues in the past," McCormick said. "I'm gluten free, and that took off weight immediately."
