Ellen DeGeneres & Portia De Rossi divorce rumors resurface after the alleged fight they had. According to Radar Online, the couple's relationship has been "tumultuous as ever" months after claims that the talk show host cheated on Portia has been exposed. Rumor suggests that the "Scandal" star has been checking in on Ellen at work and paying "unplanned visits." Could it be related to the previous cheating issues they had?

A studio source at Warner Bros. told the online publication that Portia has suddenly "begun haunting" the set of "The Ellen DeGeneres's TV Show" in Glendale, California.

"It is kind of creepy," the source tells Radar Online. "Portia never used to come to see her at work. Ellen tells us that it helps having her there because she 'at least she doesn't have to worry about her being home alone,'" the insider adds. "I have to admit, however, it seems like Portia is being slightly controlling by her unplanned visits."

According to Radar Online, control is not new to the couple. In July, Fashion N Style quoted a source from In Touch saying that Portia made the decision to check into rehab after she and her wife Ellen "got into an ugly fight" because "[de Rossi] 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 because of her controlling ways," the source added.

Over a week ago, Page Six reported that Ellen and Portia were absent in a charity fund-raiser event Saving SPOT at Tiato in Santa Monica. They were listed as the hosts of the said gathering and even have their photos present in the invitations. Reportedly, sources told them that the two cancelled their appearance "after having a huge fight in the car on the way to Sunday's event."
