Given their past Twitter feuds, it's no secret that Brandi Glanville and LeAnn Rimes are far from BFFs.

So, it doesn't come as too much of a shock to hear the Real Housewives of Beverly Hills star express how difficult it was to the see the singer caring for the two boys she has with ex-husband Eddie Cibrian.

"It's the worst pain you could ever imagine," Glanville tells Bethenny Frankel on her talk show (airing Friday, Sept. 27). "You think your heart is broken after you get a divorce? Wait until there is a girl tweeting pictures of, 'Oh, look at my family.' You have no idea."

"I feel like she almost does it to antagonize me, but at this point I've accepted it," Glanville says. "It took me awhile, but Xanax was my friend when that started happening. I was like, 'You can have the man, but those are my babies."

Glanville's divorce from Cibrian was finalized in Sept. 2010. They have two sons, Mason and Jake.

Cibrian and Rimes tied the knot on April 22, 2011.
