Getting over her divorce from Eddie Cibrian -- and the headline-grabbing LeAnn Rimes affair that led up to it -- was nothing compared to the pain Brandi Glanville has had to deal with in the months and years following, she tells Bethenny Frankel on Friday's episode of "Bethenny."

Seeing (via social media) her sons, Mason, 9, and Jake, 5, interact with their stepmother, Glanville's longtime foe, Rimes, is much worse, the "Real Housewives of Beverly Hills" star revealed. "It's the worst pain you could ever imagine," the "Drinking and Tweeting" author told Frankel. "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," she told Frankel, who is currently in a nasty divorce battle with Jason Hoppy. "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 and Cibrian, both 40, pulled the plug on their seven-year union in 2009 after Us Weekly broke the news that the actor and his "Northern Lights" co-star Rimes (who was also married at the time) were having an affair.

In the ensuing fallout, Glanville and Rimes, 31, engaged in numerous Twitter wars and have hurled nasty names and comments at each other. But despite all of the negativity, however, Glanville told Frankel that there is still a silver lining of sorts.

"You know, I think he's actually become a much better father through divorce," she said. "Because when we were together, he wasn't home a lot, he didn't spend a ton of time with the kids, and now he's really present. That's the one positive I take away from it because the rest freaking sucks."
