Brandi Glanville has been called many things - just ask her "Real Housewives of Beverly Hills" cast members - but don't call her a cheater.

Rumors have been spreading that she was having an affair with her ex-husband, Eddie Cibrian, whose new wife is LeAnn Rimes. She has been blamed for Rimes current stint in rehab for stress and anxiety.  

"I'm NOT cheating with. Y ex husband I would never do that #EWWWWWW," Glanville wrote on her Twitter page on Sept. 9.

Glanville has had a long time rivalry with Rimes who famously began her affair with Cibrian when he was still married to her and Rimes was still wed to Dean Sheremet.  

Even though the former model and "Blue" singer have taken jabs at each other via social media, Glanville has decide to support Cibrian's new wife through this hard time.

"I totally support LeAnn's decision to enter rehab," Glanville said in a statement, according to RadarOnline. "My top priority is my children and at the end of the day we are a family."

She continued by saying, "LeAnn is their stepmom, and they love her. I am wishing her all the best and I hope she will find what she is looking for while in rehab."

Rimes entered a treatment facility after a string of Twitter messages from women accusing her of being a home-wrecker.

Due to the "cyber-bullying," Rines filed suit against two women after they released a recorded phone call where she tried to dissuade the Glanville fans from attacking her on Twitter, WetPaint Entertainment reported. The pair has claimed they are the one being bullied by Rimes.

On Sept. 4, Glanville wrote, "If I sued every person that ever harassed me on twitter I'd be a GAZZILIONAIRE!" She then added, "Maybe I should sue you for this bullying tweet!! #ownurs--t."

Although, she has criticized Rimes through Twitter, she has contradicted herself and has claimed she wants to move past the cheating scandal.

On Aug. 25, she tweeted,"People PLEASE leave LR and EC stuff off my time line! Let me move forward and have an existence of my own. Thnks xxxb"
