Kyle Richards' husband isn't buying rumors of Brandi Glanville's return to The Real Housewives of Beverly Hills.

Kyle Richards Responds To 'Chopping Block' Rumors Regarding 'RHOBH'

Last night, while out in West Hollywood, Calif., realtor Mauricio Umansky was confronted with news of Glanville's possible return, which intially took him by surprise.

"What? I didn't know about this! Which country... what city?" Umansky asked the TMZ news reporter.

Then, after being informed of the alleged news that Glanville will be returning in a guest role for The Real Housewives of Beverly Hills season six, Umansky exclaimed, "She's not doing Beverly Hills!"

"No, she is not," Umansky continued. "I don't believe that story. I call bulls***. I don't think she's coming. I call bulls*** on it. That's my story, I don't know. If she is, I'll have a different opinion."

As for what that opinion would be, Umansky said, "I'd have to go ask my wife that question."

As fans have seen on the show, Umansky's wife, Richards, and Glanville haven't gotten along for years, so news of her return would likely not sit well with the Beverly Hills boutique owner.

On Thursday, E! News reported news of Glanville's rumored return to the show, noting it would not be full-time.

"She's not returning as a cast member but she's making some small appearances here and there on the new season," a source explained, "but that's it."
