One of America’s most famous lesbian “marriages” could be in serious trouble, as reports indicate actress Portia de Rossi secretly filmed her “wife,” Ellen DeGeneres, to expose the TV talk-show host’s allegedly abusive behavior.

“Portia secretly taped some of their arguments,” a source told InTouch Weekly. “She was drunk. Then she threatened to expose Ellen as controlling and manipulating.”

The source claimed DeGeneres “flew into a rage” when she found out her partner had been recording her.

The 56-year-old star of “Ellen” reportedly then combed through de Rossi’s emails to make sure she hadn’t sent the videos to anyone.

The celebrities have been married for nearly six years, after tying the knot in August 2008 at their home in Beverly Hills, California.

The latest strife is not the first time the Hollywood power couple has been reported to experience a non-blissful marriage, with previous news reports mentioning couple therapy.

“Ellen is domineering and Portia is passive. Ellen always calls the shots, and Portia never complains,” a source previously told InTouch.

“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.”

In May, the 41-year-old de Rossi, best known for her roles on “Ally McBeal” and “Arrested Development,” reportedly underwent 30 days of rehabilitation treatment for drugs and alcohol.

“Portia going to rehab was the first step in saving their marriage,” an insider said. “They want their marriage to work more than anything.”

“It won’t be easy. Portia will always be battling these demons. But they love each other.”
