Fee-fi-FOE-fum! Lisa Vanderpump joined Jenny McCarthy on her SiriusXM radio show Dirty, Sexy, Funny on Monday, Nov. 17, where the Brit revealed the identity of the culprit who slapped her in the explosive Real Housewives of Beverly Hills season five trailer. (Us Weekly revealed the trailer earlier this month.)

The no-nonsense restaurateur, 54, first called out McCarthy, 42, for comments she made while appearing on Watch What Happens Live with Brandi Glanville earlier this year. (In February, McCarthy questioned Vanderpump's motives on Andy Cohen's show. "I think Lisa's looking out for her spin-off…" McCarthy observed. "I think she's creating drama.")

Vanderpump went on Monday's show to put McCarthy in her place. "You can come on Watch What Happens Live and back me up for a change!" she joked, while the former View co-host unabashedly responded: "I'd love to call in and let's just trash Brandi. I'll be a s---starter for you."

The always-entertaining Glanville, 42, remained the main topic of conversation between Vanderpump and McCarthy on Monday. "How do you not punch some of these bitches in the face?" McCarthy commented, following up with the burning question: "Who ended up smacking you?"

"Well, your very good friend," Vanderpump responded. "The one you were on Watch What Happens Live! with — the one that you were backing."

"She hit you?!" a shocked McCarthy yelped. "Tell me you hit her back!"

While the reality TV veteran remained mum on what happened after the slap, she said the aftermath is still ongoing. "I'm not giving you final page of that book," Vanderpump said. "It was right at the end of filming, but it definitely changed the dynamic for me. I tried really hard, despite the fact that I was on that bloody show."

In Vanderpump's mind, Glanville was the outright villain of season five of RHOBH, and she believes viewers will see this side of her, too. "I knew it was one person manipulating, and I think a lot of things this season become very clear," she noted. "There's a definite kind of unveiling."

Slaps aside, Vanderpump said viewers should be prepared for a "fantastic" upcoming season. "The first episode eases in gently, but bam! It's like a runaway train."

The Real Housewives of Beverly Hills returns Tuesday, Nov. 18, at 9 p.m. ET on Bravo.
