The 'Real Housewives of Beverly Hills' star doesn't think she can ever be friends with her love rival - who began her relationship with now-husband Eddie Cibrian while he was still married to Brandi - but is hopeful they can establish an amicable relationship for the sake of her children Mason, nine, and five-year-old Jake.
Speaking about her new tell-all book, 'Drinking and Tweeting and Other Brandi Blunders', Brandi explained to 'Access Hollywood': ''I'm ready to put it behind me ... This [book] is my final chapter, this is me closing the door on our public fight. I want it out of the media, I'll just deal with it as best [as] I can with them.
''We don't have the best communication or relationship right now but, I'm hoping we can change that. I don't think we'll be friends, but I hope we can co-exist peacefully.
''I think once she has a child of her own, I think she will understand boundaries and what's respectful to do and how to handle things a little better.''
Although Brandi, 40, has previously admitted she still loves Eddie and lashed out at LeAnn, who was married to Dean Sheremet when she struck up a relationship with Eddie, she hopes the couple will remain together ''forever'' for the sake of the children.
She continued: ''They're my children. I know what's going on only 50 percent of the time that they're with them ... My children are my life, they come first.
''I don't want anything bad to happen to [Eddie] because he's the father of my children. I want him to work and flourish and I want him to stay with LeAnn forever.
''I don't want my kids to go through another divorce or breakup and I want to make sure she's stable and happy.''
