Wendy Williams, her husband and NeNe Leakes bump heads at a conference via @iam_bobokanbai

The cold war between former friends, talk show host Wendy Williams, 50 and The Real Housewives of Atlanta star NeNe Leakes, 47, erupted at The Ultimate Women's Expo at Georgia World Congress Center Atlanta on Sunday.

Not only were both women registered as keynote speakers, they also spoke back-to-back. To make matters worse, their dressing rooms were conveniently right next to each other. The whole brouhaha started when Wendy's entourage realized that her dressing room was next to NeNe's.
