Portia de Rossi filmed her fights with Ellen DeGeneres, according to reports.
The 41-year-old actress is rumoured to have entered a rehabilitation centre in May for a 30-day treatment for drugs and alcohol. The news was coupled with reports that the pair had been arguing a lot and now it seems some of those fights were caught on camera.
"Portia secretly taped some of their arguments. She was drunk," a source told InTouch Weekly. "Then she threatened to expose Ellen as controlling and manipulating."
The source goes on to say that DeGeneres "flew into a rage" when she discovered what her wife had been up to. The 56-year-old chat show host reportedly then checked de Rossi's emails to make sure she hadn't sent the videos to anyone.
The women have been married for five years after tying the knot at their Beverly Hills home in August 2008. It is not the first time that the couple have been caught up in rumours of marital strife and they have allegedly tried couples therapy.
"Ellen is domineering and Portia is passive. Ellen always calls the shots, and Portia never complains," a source previously told the publication. "She felt like a prisoner in her own home. She went from sipping white wine occasionally to drinking at least a bottle or more a day and topping it off with a pill. It got to the point where she was out of it four nights a week. They've had vicious shouting matches - with both of them yelling cruel, soul-crushing put-downs that they both deeply regretted."
But despite their recent troubles, both want to make their marriage work and DeGeneres reportedly visited her wife everyday when she was in rehab.
"They are on their way to repairing their marriage," the source said. "It won't be easy. Portia will always be battling these demons. But they love each other."
