Brandi Glanville is lashing out over online rumors that she's been having an affair with her ex-husband, Eddie Cibrian, insisting she would "never do that."
The Real Housewives of Beverly Hills star has been linked to her ex since his current wife, LeAnn Rimes, checked into a treatment facility last month.
"I'm NOT cheating with my ex husband I would never do that #EWWWWWW," Glanville, who has publicly supported Rimes, wrote on Twitter Sunday.
Glanville and Rimes have famously been at odds since her affair with Cibrian when he was still married to Brandi and LeAnn was Mrs. Dean Sheremet.
Despite a bitter relationship that included Glanvile threatening to kill LeAnn, she, Eddie and Rimes appeared to have reached a truce in recent months.
"I totally support LeAnn's decision to enter rehab," she said in a statement. "My top priority is my children and at the end of the day we are a family."
Rumors persisted that LeAnn's stress and anxiety issues stem from Glanville finally getting revenge for Rimes' wrecking her marriage to the actor.
Not the case, she insists, though the affair likely played an indirect role in driving LeAnn to seek treatment. She's endured merciless bullying over it.
The country star left her in-patient treatment program Friday for three days of concerts. She's announced she'll be returning to the facility Monday.
