Ellen DeGeneres, Portia De Rossi Divorce After Cheating Scandal Before Rehab [RUMORS]: Tell-All Book Spills Couple Secrets As Marriage Crumbles

Day time talk show host, Ellen DeGeneres and wife, Portia de Rossi may be heading towards another scandal in a new tell-all book as divorce rumors loom after Portia enters rehab in midst of cheating scandal.

The couple's relations allegedly hit the rocks after Portia entered rehab for drug and alcohol addiction. According to RadarOnline, Randy Jernigan plans on exposing the couples secrets in his new tell-all book, "The Life and Career of Ellen DeGeneres," which is set to be released in September.

The celebrity Journalist spoke to 13 of the couples close friends for exclusive information claiming that the couple haven't been stable in years, "Many fans don't know that Ellen and Portia have had a very tumultuous romance since the very beginning," Jernigan added, "They both care for each other very much," he admits, "but neither is good at the whole give and take aspect of a relationship."

According to In Touch magazine, the Arrested Development actress secretly taped the 56-year-old comedian during a drunken night in order to expose her manipulative ways during a heated argument.

One source told the magazine, "Portia secretly taped some of their arguments. She was drunk. Then she threatened to expose Ellen as controlling and manipulating." The source added,"Ellen is domineering and Portia is passive. Ellen always calls the shots, and Portia never complains. 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."

Another source claims Portia believes Ellen carried out an affair before her previous rehab stint, "She had an affair with one of their mutual friends right before Portia's rehab stint in May."

Yikes!
