Sheree Whitfield exited the Real Housewives of Atlanta at the end of season 4, and when season 5 kicks off November 4, there will be double the drama thanks to her replacements Kenya Moore and Porsha Stewart.

While RHOA's veterans are up to their old tricks -- Phaedra Parks is designing her own stun gun and doing pet funerals, and NeNe Leakes is acting in Hollywood -- it's the new wives who really make waves.

As this season 5 superteaser trailer shows, Moore and Stewart aren't exactly meshing well with the women -- or each other.

"Kenya Moore is a diva!" one insider tells Us Weekly of the Detroit native, 38, who was crowned Miss USA in 1993. "Kenya is in the middle of every fight and stirs up a lot of s--t."

During one such fight, Moore gets into it with Parks, who alleges the film and TV producer is "bi-polar . . . and drinks too much!" Not to be outdone, Atlanta-raised socialite Stewart starts her own feud with Leakes.

Watch the explosive superteaser trailer above for more from the women -- including Kim Zolciak, Kandi Burruss and Cynthia Bailey -- before The Real Housewives of Atlanta premieres November 4 on Bravo.
