Brandi Glanville and Leann Rimes might play nice at Cibrian family soccer games, but "The Real Housewives of Beverly Hills" star still had some choice words for her ex-husband's wife, Leann Rimes, on "Watch What Happens Live" Monday night.

In reference to Glanville's new book, "Drinking and Tweeting," host Andy Cohen said, "It sounds like you are inferring in the book that Leann is Eddie's kind of sugar mama."

"It's kinda true," Glanville replied.

"Do you think that now she is…" Cohen began.

"Insane?" Glanville interrupted. "Yes, I do."

"She's watching now. Hi Leann! Hi Le-Le. Call Me!" Glanville prompted.

Rimes replied with a subtle dig over Twitter, saying "Wow the texts from my friend. KISSES and KMA [Kiss my ass].

Wow the texts from my friend. KISSES and KMA
