Ellen DeGeneres and Portia de Rossi divorce and cheating rumors have been making the rounds in the tabloids. Some magazines have said that Ellen has had meltdowns that led Portia to do a stint in rehab.

A new report says that Ellen cheated on Portia right before she went into rehab stay. The tabloids are reporting that Portia thinks that Ellen had an affair with a mutual friend in May.

But if these rumors are true, why are Ellen and Portia going about their normal lives doing regular things that married couples do.

Last week, the Los Angeles Times reported that Ellen sold her Los Angeles trophy home, which she and Portia bought for $40 million, to Sean Parker, who founded Napster, for $55 million. The mansion nine bedrooms and 7 and a half bathrooms.

Yet and still, InTouch Weekly claims that Portia thinks Ellen had an affair.

"Portia thinks that Ellen had an affair with one of their mutual friends right before Portia's rehab stint in May, " a source told the magazine.

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

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

Classicalite quoted a source who said "[Portia] can't get the phrase, 'Once a cheater, always a cheater,' out of her mind. It's going to take a lot for Portia to trust Ellen again... There is still so much tension between them. And Ellen still drinks in front of Portia - that doesn't help. Portia is having huge problems forgiving Ellen for betraying her."

"Ellen wants to honor Portia, her struggles and their love together after all they've been through. They kept up with the therapy after Portia got out of rehab, but they still have a long way to go. They may never really find their way back to each other," the source continued.
