Publicly, Ellen DeGeneres and Portia de Rossi‘s marriage looks picture perfect, but behind closed doors, it’s a completely different story.

Even though it’s purely innocent, the Arrested Development star can’t help but feel jealous when the talk show flirts with other actresses.

“Portia is convinced that Ellen has so many friendships with sexy movie stars to get under her skin,” says the insider. “She thinks Ellen does it on purpose to make her feel insecure so she doesn’t leave.”

The tension between the couple, who have been married for nearly nine years, was visible when Ellen and Portia stopped by Craig’s restaurant in West Hollywood recently.

“Ellen seemed miserable and Portia just looked sad,” says one patron. “‘Happy’ isn’t the first word I would use to describe them,” adds a Craig’s staffer.

However, the pair continues to deny divorce rumors.

“We’re just really good friends and we talk about everything, and we never ever, ever lie to each other, like, not even the tiniest lies,” Portia told ET last year. “And she’s the only person I want to hang out with. Like, she is my best friend and I just want to be with her all the time.”
