Jessica Biel flaunted a very special accessory while out celebrating in New York City Saturday night.
More than a month since news broke of her engagement to Justin Timberlake, the actress was spotted wearing what appeared to be her engagement ring – and 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 – never mind a rare public display of affection for the couple who don’t often step out together.
Biel, 29, and Timberlake, 31, “were very lovey all night and kissed a few times,” a guest at the Ristorante Asellina party tells PEOPLE.
