Is there trouble in paradise again in Ellen DeGeneres's marriage to Portia de Rossi? According to National Enquirer (via Gossip Cop), the pair have an explosive fight over food after a party for the talk show host's 20-year anniversary of coming out.

"Ellen and Portia's Ugly Anniversary Blow Up," so reads a headline from this week's issue of the magazine. It claims the couple's locked in an explosive public bust-up outside a Beverly Hills restaurant after celebrating "The Ellen DeGeneres Show" host's "coming-out milestone."

A so-called source, who allegedly witnessed the fight, tells the publication, "Portia kept trying to talk to Ellen, but Ellen wouldn't even look at her as she screeched out of the parking lot." The alleged insider goes on to claim that their argument started over Portia only ordering soup during dinner.

"Even though Portia is through the worst of her eating disorder, Ellen watches every bite she takes," explains the supposed eyewitness. The source adds that the famous host started "lecturing" her actress wife about eating something more "substantial," before concluding, "By the end of the meal, they were both seething."

It's not the first time Ellen and Portia have been slapped with rumors about having marital problems. Recently, the 44-year-old actress was said to be cutting her wrists as a result of her marital crisis with the 59-year-old host. As of now, reps for the couple have yet responded to a request for comments.
