Is life imitating art for Jerry Ferrara (who plays Turtle on Entourage) and his on-screen love interest Jamie-Lynn Sigler?

Though they haven’t confirmed it officially, the two did seem to out themselves earlier this week—leaving Chateau Marmont hand in hand for all photogs to see.

Besides, it's obvious Jamie-Lynn and Jerry are an item, says costar Kevin Connolly. 

"I cannot speak to that, but listen, look around; the writing's on the wall," Kevin tells E! News.

Connolly said at his directorial debut of Blackcowboy's music video "Come On" at the Viper room Wednesday night that he didn't want to "out" his buddy, but added that anyone who is coherent should be able to tell what's going on between the onscreen lovers.

When asked if they are indeed a couple, Connolly said, "It looks that way to me. I don't want to confirm anything, but it certainly looks that way."

A rep for Ferrara told E! News, "I honestly don't know," when asked to confirm their relationship. Sigler's rep did not return calls for confirmation.
