Brandi Glanville hit out at Eddie Cibrian on Twitter for preventing her from getting in contact with their sons.
The 'Real Housewives of Beverly Hills' star bashed the actor on Twitter for preventing her from speaking to their sons, Mason, nine, and Jake, five, while they were staying with him and his wife Leann Rimes.
The 40-year-old blonde author expressed her frustration in a message to Eddie on Twitter on Monday night (20.05.13) writing: ''Ive been trying to get a hold of my kids 4 over an hour no response to my calls, emails or messages. Maybe twitter will work (sic).''
The tweet provoked a defensive response from LeAnn, who soon wrote: ''Funny, she just got off the phone w/ them. Sorry, we were doing baths, homework & dinner. All good!
''The phone rang, I picked it up. Never saw this til after. All you gotta do is call.''
The furious exchange took place shortly after LeAnn revealed that the boys couldn't stop singing a line from a song from her new album, 'Spitfire', about her affair with Eddie that led to the end of both of their first marriages.
She tweeted: ''They walk around singing 'I don't want to give you back.' It's the hooks.''
Brandi previously revealed she believes her acrimonious relationship with LeAnn will drastically improve once the singer gets pregnant because it will help her to learn boundaries as a mother and stepmother.
The 'Drinking and Tweeting and Other Brandi Blunders' author said: ''Hopefully, they'll have a child of their own and she'll understand better what a proper boundary is for a stepmother and a mother.''
The rivals were recently thought to have ended their feud after LeAnn sent Brandi flowers for Mother's Day earlier this month.
