Now it seems as though their sunny public appearances may have been masking some serious serious marital troubles:
In Touch reports that Portia checked into a Malibu treatment facility in May to try and kick her drug and alcohol addictions.
Her decision to seek help was reportedly the result of a realization that her bad habits were destroying her marriage.
"They got into an ugly fight," a source tells the tabloid. "Portia hadn't been happy for a while and was drinking and isolating [herself] and Ellen confronted her. Portia lost it and blamed Ellen for driving her to drink."
The magazine claims that Portia sought treatment just days after that blow-out fight.
DeGeneres reportedly visited de Rossi "every weekend," and Portia has now completed treatment, but all is still not well for the mega-rich talk show queen and the Arrested Development star:
"Ellen is domineering and Portia is passive," says the insider. "They're on their way to repairing their marriage, but it won't be easy. Portia will always be battling these demons."
Iâ€™m thrilled that the California supreme court overturned the ban on gay marriage. I canâ€™t wait to get married. We all deserve the same rights, and I believe that someday weâ€™ll look back on this and not allowing gays to marry will seem as absurd as not allowing women to vote.
