Jessica Biel shows off her engagement ring from Justin Timberlake

Jessica Biel should have worn her engagement ring sooner. A source who attended the “Saturday Night Live” after-party at Asellina early Sunday morning tells us that the actress’ engagement ring from Justin Timberlake, which she has never worn in public, was the talk of the soiree.

The guest says “SNL” alum Amy Poehler, who returned for a special appearance, and Kristin Wiig “loved the ring and chatted her up about it” at the Gansevoort Park hotel’s eatery.

Our insider says Biel and Timberlake — who reportedly got engaged in late December — were “very lovey” and “kissed a few times” at the shindig. The source adds that when Maya Rudolph, who hosted, made her entrance, she got a big round of applause from a crowd that included nJason Sudeikis, Philip Seymour Hoffman, Sports Illustrated cover girl Kate Upton and Evan Rachel Wood.

Avril Lavigne and Brody Jenner have called it quits — but not in the biblical sense. A source close to the couple tells us that though the “Keep Holding On” singer and Jenner called off their two-year relationship last month, “they’re together so much you would think (they’re still a couple).” The insider clarifies, however, that right now, Lavigne and Jenner are just “friends with benefits.”

Lauren Conrad chose an interesting flirting partner at her 26th-birthday party on Thursday. According to a source at the soiree, Conrad — formerly with MTV’s “The Hills” reality show — raised eyebrows at her masquerade birthday bash at Redbury in Los Angeles when she spent quality time flirting one-on-one with 38-year-old actor (and New York Fashion Week staple) Stephen Dorff. Our insider says Conrad seemed really taken with the “Somewhere” star, although we hear her friends didn’t approve.

They don't make New Yorkers like Steven Greenberg anymore. The snowy-haired Renaissance man was as idiosyncratic, opinionated and hype-savvy as they come and well-known across a remarkable swath of the city’s subcultures. Greenberg owned the rooftop hot spot 230 Fifth Avenue, and in previous years, the Roxy nightclub, but he’d also made a name on Wall St. and publishing as the founder of Fame magazine. On Monday, hotelier Ian Schrager, Elizabeth Ray, former Fame editor Roger Friedman and Greenberg’s business partner Michael Scharf gathered at the Riverside Memorial Chapel, where Scharf recalled that Greenberg carried only $100 bills, perhaps because he had an “affinity” for Ben Franklin, with whom he shared more than a passing resemblance.

Terry George will have a lot of kin to thank if his film, “The Shore,” wins the Academy Award for Best Live Action Short. The filmmaker enlisted his daughter, Oorlagh, as a producer; son, Seamus, as an assistant director, and sister, Catherine, as a costume designer. When he needed extras in the Northern Ireland town of Killough, he called his relatives. “I even squeezed in the cemetery where my mother and father are buried,” George says. “The Corleones couldn’t compete with us as a family enterprise.” The movie plays, along with the rest of the Oscar-nominated shorts, at the IFC Center on Sixth Ave. through Sunday.
