Sorry Entourage fans, you can just fuhgeddabout about off-screen lovers Jamie-Lynn Sigler and Jerry Ferrera. The stars, who began dating in October 2008, may have broken up, a source close to The Sopranos actress says.

Rumors started swirling that the couple had taken up residence in Splitsville when Jamie-Lynn showed up sans manbag for last Tuesday’s screening of It’s Complicated at the W Hotel in Los Angeles.

“It was mutual and they’ll still be friends,” says a tattle. “It’s just that things were getting serious too fast.” While looking at houses together, says the source, both Jamie-Lynn — whose brief marriage to A. J. DiScala ended in divorce — and Jerry decided they weren’t quite ready to settle down,” the spy adds.

“I wouldn’t be surprised if they end up together a few months from now, but they needed a little break.”
