American talk show host and comedian Ellen DeGeneres and Portia de Rossi are allegedly headed for a $350 million divorce. According to a report in Radar Online, the 44-year-old actress has moved out of the home she shares with the Oscar host, and is staying at a mansion located in Beverly Hills.

An alleged source told the website: "Portia is tired with being the stay-at-home wife, while Ellen gets the big career and all the attention. Things reached the boiling point a few weeks ago, and after their worst fight ever, Portia packed up and headed to a secluded home they secretly bought in Beverly Hills months ago."

"Portia has been holed up there for a couple of weeks, refusing to go back home to Montecito where Ellen's been stewing during her downtime from her talk show," the insider added. "Portia's inviting her lesbian friends over for girls' nights in, ordering takeout, staying up late and sleeping in. It's been heaven for her."

"They [DeGeneres and Rossi] bought the house for a quick turnover, but Portia's thinking she may stay a while. She's picking out new curtains, and making things really comfy. Portia's refusing to give in to Ellen until things change," the source said.

The couple allegedly distanced after a controversial interview by DeGeneres' former girlfriend, Anne Heche, who accused the Finding Dory star of forcing Rossi to give up her career. The insider said: "The fight started when Ellen complained about something Portia did that irritated her. Portia got real defensive and brought up that Anne Heche interview."

Heche's comments "really made Portia think. She feels like she's been taken for granted so long, and that Ellen is so controlling. Anne's words have really stuck in her craw."

"It hurts Portia that Ellen isn't more supportive of her acting career, and they don't seem to have anything in common anymore. They spend less and less time together. In fact, they've been living separate lives for over a year. It's gotten so bad that they hardly say a word to each other all day," the source revealed.

However, DeGeneres has previously slammed reports that she and Rossi are heading for divorce. She said, according to Entertainment Tonight: "We don't know anything about it until somebody tells us. I don't read the tabloids, and I don't have a publicist."

"I don't know why they do this," DeGeneres added. "We're kind of flattered. We really don't almost break up, we don't fight, we're madly in love, and I guess it's boring."
