As In Touch previously reported, Ellen Degeneres and Portia de Rossi's marriage has been rocky for quite some time. With accusations of cheating and stints in rehab, the two women have been attempting to work through this rough patch.

Ellen and Portia seemed to be on the right path to fixing their six-year marriage, but an insider tells In Touch that the couple are facing hardship yet again.

The two recently returned from a South African vacation, and since their return, the blonde beauties have been fighting non-stop. "Right after they got back, they had a huge fight about Portia's career," says a source. "Portia told Ellen that once she starts filming Scandal again, she'll be married to her job."

It was a blow to the talk show queen, 57, who has allegedly been controlling and possessive of her actress wife, 42, for quite some time. "They wound up in a big screaming match and didn't speak again for days," adds the source.

"It doesn't look like they will ever be able to get back on track. Ellen and Portia will soon be living separate lives."
