Kelly Bensimon might have been trying a little too hard to get noticed at Gotham magazine’s 100 Hottest Eligible Bachelors party at the M2 club. Raising her arm to wave goodbye, the “Real Housewives” star “accidentally” revealed she was “commando.” A spy laughed, “She was wearing the smallest shirt as a dress ever. So when she put her hand up, her bare bottom was exposed. She said ‘Oops!’ and started giggling. She didn’t seem like she minded.” Bensimon cast mates Jill Zarin, Alex McCord and newcomer Sonja Morgan were also there — and more fully clothed.
