Brandi, in her appearance on Monday night’s edition of Watch What Happens Live, called LeAnn "insane;" says she's husband Eddie Cibrian's "Sugar Mama;" claims LeAnn obsessively watches her on The Real Housewives Of Beverly Hills, and knocked the singer's ongoing stream of personal interviews ("Everyday there's a tell-all!").
So, after a month of rehab, was LeAnn able to turn the other cheek after being bashed on TV?
"Wow the texts from my friend," the How Do I Live singer tweeted while the show was airing on the West Coast. "KISSES and KMA," as in, "Kiss My A**."
Brandi wrote, "I love you.. No! U! Yes I really do!!!! Im in love with my twitter and i will NEVER leave u for 'tweehab' gdnt biddy!"
Brandi's new book Drinking & Tweeting comes out February 13, while LeAnn's new album, Spitfire, hits stores April 9.
