Of Beverly Hills, she said the ongoing with between Brandi Glanville and Lisa Vanderpump -- which has dominated much of this season's storyline -- has been "pathetic" on Brandi's behalf, as she made no bones about which side she's taking.

"I'm on Lisa's side!" the beauty said, adding she's known the Vanderpump Rules star since she was 7-years-old.

Moving onto Atlanta, there was the question about Mama Joyce, Kandi Burruss' meddling, helicopter mother who's never short of a strong opinion about her daughter's love life or life, in general.

"I don't want to be disrespectful to her mother, but Mama Joyce has way overstepped her boundaries."

Asked about Porsha Stewart, Naomi said the reality star should be "a little ashamed" about her infamous Underground Railroad railroad flub; she stopped short of casting any aspersions about her break up from former NFL star Kordell Stewart.

"Oh God, do I have to answer this question?" Naomi joked, before delivering a diplomatic soundbite about how Porsha seems to be adapting to the single life well.
