Brandi Glanville and Eddie Cibrian's marriage ended nearly four years ago but it still seems they are not on amicable terms.

The 'Real Housewives of Beverly Hills' star took to twitter to rant about her ex-husband, and his most recent demands, while promoting her new book.

Glenville claims that Cibrian, with whom she shares two sons, Mason and Jake, is still asking for child support.

"2 all these young unmarried bloggers writing about getting over divorce & not seeing ur children grow up 1/2 the time, walk a mile in my shoes," she tweeted on Tuesday (Feb 18th).

"I'm not taking cheap shots at my ex in my new book cuz it's all true & now mr fancy new cars & house man is asking me for child support! U know nada," Glanville continued.

"Everytime I take 1 step frwd I get a lawyers letter that takes me 3 steps back so wen people say move on, I say 2 my ex LET ME! Just STOP," she later posted. "Going to stay positive and focus on my new book & let my lawyer handle the rest."

Cibrian, who is an actor and recently had a role in 'The Best Man Holiday', has responded through his rep since these accusations were made.

"There is no truth to the claims that Eddie has requested child support from Brandi now, nor will he ever request child support from his ex-wife," the 40 year-old's rep told Us Weekly in a statement. "The notion is preposterous. This is yet another ploy for self-promotion."

Glenville and Cibrian divorced back in 2010 after he reportedly cheated on her with his current-wife and singer LeAnn Rimes.

People reports, a source close to the mother of two said, "Now that Brandi is making money and is successful, Eddie is backtracking on a prior agreement they had regarding child support payments. He's asking for money back from her, over $100,000, saying he overpaid. But he's asking for more than he's paid her in the first place!"
