Once a cheater always a cheater! It’s no secret Eddie Cibrian and LeAnn Rimes had an affair while he was married to Brandi Glanville, and it appears the 'RHOBH' star is STILL out for blood when it comes to her ex-husband!

On her podcast, Brandi spoke with Dean McDermott’s ex-wife, Mary Jo Eustace, and opened up about the end of her marriage. The mom-of-two claims Eddie, who would leave for “weeks at a time” and “sleep in separate rooms” from his reality star ex, tried to win her back and claimed he still loved her — even though he was romantically involved with his 'Northern Lights' costar (and now wife) at the time!

Hmm, sounds like someone always wants what he can't have!

Brandi states she “may have” recorded these convos and sent them to LeAnn, who was also cheating on her then-husband.

Despite this alleged knowledge, the couple are still happily married.
