The couple hosted a star-studded holiday bash at their Los Angeles home on Saturday night, which Entertainment Tonight reports was attended by the likes of Doja Cat, Kim Kardashian, Billie Eilish, Eric André and more.
Videos shared to social media show Lopez, 53, leading the crowd in a sweet rendition of “Jingle Bells,” wearing a stunning long-sleeved gold gown and holding the microphone out to those gathered around amid a backdrop of twinkling lights and Christmas trees.
This is the first holiday season Affleck and Lopez have shared since marrying earlier this year, after an initial engagement in the early 2000s and reconnecting romantically last year.

The couple tied the knot on July 16, during a private Las Vegas ceremony at the Little White Wedding Chapel.
“It’s a beautiful outcome that this has happened in this way at this time in our lives where we can really appreciate and celebrate each other and respect each other,” Lopez told PEOPLE earlier this year of her and Affleck’s second chance at love.
The Grammy nominee added, “We always did, but we have even more of an appreciation because we know that life can take you in different directions.”
The pair spent the holidays last year surrounded by family, including their children.
