Morning Joe co-host Mika Brzezinski sat on a panel at the Women of the World conference over the weekend and was so moved by the discussion over makeup that she decided to do something rather unprecedented -- take it all off.

She recounted the incident earlier this week. Amid cheers of "take it all off," Brzezinski began wiping off her makeup while on stage. 'You guys would not believe me without make-up,' she said. Should I take my make-up off? We were talking about how make-up is... it's powerful, and we become addicted to it," she said. '"And so I took it all off on stage, and it was fun."

Brzezinski also told of an instant when she was actually denied entry into the CBS building because she wasn't wearing makeup and the security guards didn't recognize her -- despite the fact that she regularly appears on the network's shows.

Brzezinski has been refreshingly honest about her past struggles. She'd previously opened up about an eating disorder she'd had in her youth. [Daily Mail]
