Goodbye Sheree, hello Kenya and Porsha!

On Thursday, Bravo announced the revamped cast of the Real Housewives of Atlanta as it gears up for the November premiere of season five. As previously revealed, Sheree Whitfeld departed the reality smash after last season -- and Whitfeld has been replaced by not one but two Southern belles.

Newcomer number one Kenya Moore's biggest claim to fame so far? The single Detroit native, 38, was crowned Miss USA in 1993, and is now works as a film and TV producer via her company, Moore Vision Media.

"Kenya Moore is diva!" one insider tells Us Weekly. "Kenya is in the middle of every fight and stirs up a lot of s***."

Entering the fray alongside Moore is Porsha Stewart, is an Atlanta-raised socialite now married to NFL star Kordell Stewart and mom to stepson Syre.

Predictably, Moore and Stewart don't exactly get along, the insider says: "Kenya has it out for [Porsha]."

Moore and Porsha join returning castmembers NeNe Leakes (now a budding Hollywood actress thanks to her role in TV's The New Normal), Kim Zolciak (she gave birth to her fourth child last month), lawyer/mortician Phaedra Parks, musician/entrepreneur Kandi Burruss and model Cynthia Bailey.
