Jessica Biel has yet to confirm her engagement to Justin Timberlake with a ring, but it seems she was flashing around some impressive bling Saturday night.

Us Weekly reported the Seventh Heaven actress attended a Saturday Night Live after-party with Timberlake, who appeared in a few sketches that night with host Maya Rudolph.

According to People magazine,
sources said the two were seen getting very cozy and cuddly at the party, which took place at Ristorante Asellina.

An attendee said the 29-year-old and her 31-year-old beau were very lovey all night and kissed a few times," which is surprising given the two are very private and do not usually attend public events together.

Biel and Timberlake, who had been dating on and off since 2007 before he popped the question a month ago, were joined by Amy Poehler, Evan Rachel Wood, Jamie Bell, Kate Upton, David Alan Grier, Seth Meyers, Chlo Sevigny, Natasha Lyonne, Andy Samberg, Jason Sudeikis, Philip Seymour Hoffman, Kenan Thompson and Rudolph at the party.

Kristen Wiig was also at the fete, and reportedly gushed over Biels ring. A source said she loved the ring and chatted [Biel] up about it."

Biels rep has yet to confirm the story.
