Brandi implied LeAnn's been crying wolf with her cavalcade of emotional, no-holds-barred interviews - the latest with Entertainment Tonight, in which she discussed her fears of losing husband Eddie Cibrian, and her stint in rehab for stress and anxiety.
"Everyday there's a tell-all," Brandi said. "It's kind of cray-cray!"
"It's true, yeah," Brandi said, confirming that Eddie had always wanted to live in a big house in an affluent community - two wishes the How Do I Live singer has been able to grant with her wealth.
Asked point blank if she though LeAnn was insane, Brandi said, "Insane? Yes I do!"
Brandi said she knows LeAnn religiously watches her antics on The Real Housewives Of Beverly Hills, recalling how her son Jake saw Andy on TV and said, "That's LeAnn's favorite show!"
"I hope LeAnn will come on!" Andy said.
The jury remains to be seen on that: During the broadcast, LeAnn took to Twitter to (presumably) respond to Brandi, writing, "Wow the texts from my friend. KISSES and KMA," as in, "Kiss My A**."
Brandi's new book Drinking & Tweeting comes out February 13, while LeAnn's new album, Spitfire, hits stores April 9.
