It's "The Talls" versus "The Smalls," round 1!

Bravo just released a preview of their three (!) part "Real Housewives of Atlanta" reunion, and the gloves are off!

In one corner are "The Talls:" NeNe Leakes, Cynthia Bailey and "friend of the Housewives" Marlo Hampton; in the other are "The Smalls:" Kim Zolciak, Sheree Whitfield, Phaedra Parks and Kandi Burruss.

Watch as Sheree and NeNe's feud reaches a boiling point, Marlo calls Kim a "whore" (um pot, meet kettle), and Kandi rocks a brand new hairstyle!

As host Andy Cohen would say, it's unbe-weave-able!

Part 1 of the "Real Housewives of Atlanta" reunion airs this Sunday on Bravo. It may be the last you'll see of Sheree Whitfield, as she's reportedly been axed from Season 5.
