The bickering blondes have put their fighting gloves on once again after Brandi Glanville publicly insulted LeAnn Rimes.

For those who haven’t been following the “Real Housewives of Beverly Hills” drama, the 30-year-old country crooner essentially stole her now-husband Eddie Cibrian away from Glanville, 40.

The award-winning Rimes and Cibrian, 39, were both in relationships when the affair started.

"I feel like every day there's a tell-all interview," Glanville told Bravo host Andy Cohen on Monday night's "Watch What Happens Live." "It's kind of cray-cray."

Rimes recently revealed the insecurities she has in her marriage, explaining on “Entertainment Tonight” that since Cibrian cheated on his ex-wife with Rimes, he might be unfaithful to her too.

"I would be ignorant to say, and everyone else would think I am a liar if I didn't say yes, and I have at times," Rimes said.

The singer and Cibrian met on the set of the Lifetime movie “Northern Lights” three years ago. The actor ended his marriage with Glanville and Rimes divorced her husband Dean Sheremet.

The “RHOBH” star has publicly stated that Rimes is just Cibrian’s “sugar mama” and has had public Twitter wars with her ex over their children.

While continuing the interview with Cohen, Glanville revealed:

“[Do I think she’s] insane? Yes, I do.”

Rimes refused to let the insult go unanswered, and took to Twitter:

"Wow the texts from my friends. KISSES and KMA," she tweeted.

For those who haven’t ever had a public feud on Twitter, KMA stands for kiss my a**.

Glanville’s new book, “Drinking and Tweeting” drops in stores on Feb. 13.
