Here are some new pictures of Jessica Biel and Justin Timberlake, as they both leave a doctor’s office at the UCLA Medical Office Building. In each of the pictures, Jessica’s concealing her left hand – therefor her new engagement ring! According to several sources, however, Jessica proudly showed off her ring on Saturday night at a wrap party for ‘Saturday Night Live’.

At the after party held at  Asellina in Ganesvoort Park Hotel, ”Jessica was showing off her ring,” the source tells Us. The pair were engaged over the holidays in Jackson, Wyoming.  ”They were very lovey. Holding hands,” another source tells Us of Biel and Timberlake’s PDA at the soiree. “They kissed a few times in front of the crew.”

Justin made a surprise appearance on Saturday Night Live over the weekend. The episode, which was hosted by Maya Rudoplh, had several celebrity guest appearances. More from HuffPo:

Rudolph reprised her Beyonce impression and Jay Pharaoh tackled Jay Z in a sketch where they show off their new baby to their world-renowned friends. One by one they all show up, including Prince (Fred Armisen), Nicki Minaj (Nasim Pedrad), Taylor Swift (Kristen Wiig) and, finally, Grammy Award-winning Bon Iver frontman Justin Vernon, played by ‘SNL’ favorite Justin Timberlake.

Anyone who listens to Bon Iver (or Googled it last week) will get a kick out of Timberlake’s impression as he serenades the world’s most talked-about infant. Let’s just say he’s the perfect person to have around when you need a lullaby.

I love JT on SNL. He’s absolutely hilarious! Watch his clip below!
