Selena Gomez, Benny Blanco celebrate Hanukkah with starry party: Erin Lichy, Debra Messing, more

Happy challah-days!

Selena Gomez and Benny Blanco celebrated the first night of Hanukkah, which happened to fall on Christmas Day this year, at a star-studded Festival of Lights party in New York City on Wednesday.

The pop star and her new fiancé hung on a couch at the festive fête in a slideshow of videos and photos posted to cookbook author Jake Cohen’s Instagram on Thursday.

“Some lonely Jews on Christmas getting lit,” Cohen captioned the post.

Gomez, 32, looked cozy and casual in a snowflake-print pajama set and a white knit beanie as she cuddled up to the music producer.

Blanco, 36, looked equally comfortable in white pants and a cream sweater with a stuffed animal dog tucked into the breast pocket.

Also spotted celebrating the holiday were “Real Housewives of New York City” star Erin Lichy, actress Debra Messing, TV writer Jenji Kohan, comedian Alex Edelman, composer Benj Pasek, podcaster Amanda Hirsch and foodies Adeena Sussman and Michael Solomonov.

In one snap, Lichy, 37, hugged Messing, 56, while another image showed Cohen posing in front of a table topped with several challahs, a large bowl of hummus, plates of cookies and boxes of jelly doughnuts called sufganiyot.

Other videos captured Blanco dancing the hora with friends as a band played “Hava Nagila” as well as the “Will and Grace” alum giving a funny speech for partygoers.

Edelman, who won an Emmy earlier this year for his HBO stand-up special, wore a red Christmas onesie and a yarmulke while lighting the menorahs along with Cohen, 30, and Pasek, 39.

Hirsch, 36, posted a video of herself enjoying a beverage with entrepreneur Moti Ankari as the band played some upbeat tunes.

“Ain’t a party until ‘Sweet Caroline’ comes on,” the “Not Skinny But Not Fat” host captioned the Instagram Story post.

Blanco, who proposed to Gomez earlier this month, is Jewish and often wears a Star of David necklace.

Gomez, for her part, still celebrated Christmas and posted a photo of presents and her dog under her tree.

She also shared a selfie with “How I Met Your Mother” actor Josh Radnor to her Instagram Story after running into him over the holidays.

“Made my Christmas @joshradnor,” the singer captioned the photo, adding that she is a “huge fan” of Radnor’s sitcom.
