"Real Housewives of Atlanta" may have just found its two newest cast members in Will Ferrell and Maya Rudolph.

The two stars appeared on Sunday night's episode of "Watch What Happens Live ," where host Andy Cohen had them play a game of "Clubhouse Playhouse." During the segment, Cohen gave them each wigs and asked them to perform a scene between Kenya Moore (played by Ferrell) and Sheree Whitfield (played by Rudolph) from "RHOA."

Things got heated pretty quickly as Ferrell's Moore told Rudolph's Whitfield that all their neighbors are fed up and complaining about the construction of her new home.

"I am building Chateau Sheree," Rudolph explained. "Anybody who's built a house before, well, then they can probably come to me, but if they have not then probably keep wrenching."

When Ferrell quipped, "Actually, it takes about six months to build a house from the ground up," Rudolph sent the sass right back.

"Have you moved in?" she asked.

Of course, Ferrell said, "Not yet," which warranted the response, "Let me know when you finish your mold-infested house. No one should be in my business."

Fighting words!
