First rehab and now cheating allegations and couples therapy? The rumors keep rolling in when it comes to Ellen DeGeneres and Portia de Rossi's marriage.

In Touch, which broke the story claiming that Portia spent 30 days in a treatment facility in Malibu, Calif., is back with another shocking story citing sources who claim that Portia believes Ellen cheated on her before she went to rehab. And presumably because of all the marital turmoil, the couple is now sitting down on a leather sofa somewhere, receiving couples therapy.

"It's going to take a lot for Portia to trust Ellen again," a source told In Touch. "They kept up with the therapy after Portia got out of rehab, but they still have a long way to go."

Back to that affair. In Touch writes that Ellen's alleged dalliance was "with one of their mutual friends right before Portia's rehab stint in May," according to a source.

This isn't the first -- or even the 100th -- time that the duo have seen their names attached to headlines declaring marital turmoil. Tabloid chatter has followed them consistently since they tied the knot in 2008. Ellen addressed one of the reports during a sit-down chat with People in February, putting to rest any lingering questions of their commitment to one another.

"The truth is, and this is corny, I fall more in love with Portia all the time. I really do. She surprises me all the time," she said. "It's what anyone experiences when you find that person that gets you, wants to take care of you, wants the best for you. We're really lucky because we know how rare it is," she told the mag.
