Jessica Biel flaunted a very special accessory while out and celebrating in New York City last Saturday night. It has been more than a month since the news broke about her engagement to Justin Timberlake. The actress was spotted wearing and probably showing off what appeared to be her engagement ring. Biel was also seen getting cozy with her man at a "Saturday Night Live" after-party.

This would mark the first time Biel went out in public with her sparkler with a rare public display of affection for the couple who do not often step out together. "The couple was very lovely all night and kissed a few times," a guest at the Ristorante Asellina party tells People.

The couple, who started dating in 2007, celebrated Timberlake's appearance on "Saturday Night Live" as Grammy-winning folk sensation Bon Iver with guests such as Evan Rachel Wood and rumored fiance Jamie Bell, "Sports Illustrated" cover girl Kate Upton, David Alan Grier, Seth Meyers, Chloë Sevigny, Natasha Lyonne, Andy Samberg, Jason Sudeikis, Philip Seymour Hoffman, Kenan Thompson and the show's host and alum, Maya Rudolph.

Also spending time with the couple is former "Saturday Night Live" star Amy Poehler and current cast mate Kristen Wiig, who, according to the source, loved Jessica Biel's ring and chatted with the actress about it. However, a representative for Biel could not be reached for comment or confirmation regarding the engagement.
