Brandi Glanville thinks Eddie Cibrian will cheat on LeAnn Rimes.

The 'Real Housewives of Beverly Hills' star - who has two sons, Jake, six, and Mason, 10, with her ex-husband - doesn't think he will be able to stay faithful to the country singer, whom he first got together with when he was still married to Brandi.

The 41-year-old reality TV star told California radio station Q104.5's 'Up & Adam in the Morning': "I hope that I'm wrong, but I do feel that [the saying] 'Once a cheater, always a cheater' applies in this instance.

"I feel like once you cross that line, it's easier to do another time, but I hope not."

The 'Drinking & Dating: P.S. Social Media is Ruining Romance' author accused Eddie, who recently bought a new $3 million home with LeAnn, of asking her for child support earlier this week.

She wrote on Twitter: "Im not taking cheap shots at my ex in my new book cuz its all true,&now mr fancy new cars&house man is asking ME for child support!Uknownada

"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 (sic)"

But a spokesperson for Eddie, 40, told gossip website RadarOnline.com: "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 notion is preposterous. This is yet another ploy for self-promotion."
