Ellen DeGeneres and Portia de Rossi have been "fighting non-stop" since returning from their South African vacation, putting their efforts at reconciling their rumored strained marriage again in jeopardy.

In Touch Weekly reports soon after returning to the U.S., the two had a huge fight about de Rossi's career. The website adds that blowup comes on top of recent ones stemming from accusations of cheating and rampant drug use.

"Portia told Ellen that once she starts filming 'Scandal' again, she'll be married to her job," a source told In Touch of what led to the most recent dispute.

Apparently, that news came as a complete and bitter shock to 57-year-old DeGeneres, who has long been rumored to seemingly control her wife's every move.

"They wound up in a big screaming match and didn't speak again for days," the source added. "It doesn't look like they will ever be able to get back on track. Ellen and Portia will soon be living separate lives."

According to RadarOnline, de Rossi had been recently pressuring DeGeneres to cut back on her workload so the two could spend more time together working on their union. The 42-year-old veteran actress was only recently released from rehab for a drug and alcohol addiction.

DeGeneres' current talk show deal expires in 2017, and she reportedly has already told staffers this may spell the end.

"Ellen's contract is up in 2017, and she has told her staff that she does not know if she is going to renew it," a source said of the show that has aired since 2003 and is one of daytime's longest-running talkshows. "Everyone on the staff is just freaking out over this."

As for de Rossi, a source added she's not nearly as nice and gracious to staffers when she comes to the studio as she once was. "She seems to really resent the show and everyone who works there," the source added.
