DuringSunday's volatile tour bus blow-up with Kim Zolciak, days later, NeNe Leakes admits that she's embarrassed by her actions. "It's an embarrassing thing to see as a mother and as an adult," Leakes tells TVGuide.com. "I apologize to my viewers and fans, and to my children and family and friends who love and care about me. ...I apologize to them for them having to see me stoop to such a trashy level. When you fool with trash, it can get all over you." Leakes and the pregnant Zolciak got heated on the Real Housewives of Atlanta episode during a confrontation over the way Zolciak treated her longtime assistant, Sweetie Hughes. The pair's latest altercation comes a year and a half after Zolciak filed a police report against Leakes, alleging that her Bravo reality costar "strangled" her.
