And this is why you either love Brandi (or think she’s a tad too unguarded).

At a Villa Blanca Mother’s Day brunch which was thrown by Lisa Vanderpump and Ken’s daughter Pandora, the always outspoken Beverly Hills Housewife interrupted an interview bachelor Sean’s fiance Catherine Giudici was giving to In Touch magazine.

“I hate that your fiance is having an affair with Peta,” Brandi said. “But you guys will have the best threesomes!”

No doubt the 40-year-old Housewife was referring to the palpable energy between Sean and his Dancing with the Stars partner Peta Murgatroyd.

Catherine responded with a sarcastic, “Thanks, Brandi, thanks.” 

Even though it sounds like Catherine knew Brandi was kidding, she took to Twitter to clear it up, just in case.:

I was clearly joking with @clmgiudici about the 3somes thing! We both laughed some people are so uptight!
