Jennifer Lopez gets nightclub ‘buzzing’ with surprise performance during Sundance Film Festival

Jennifer Lopez still knows how to get clubgoers on the floor!

A source tells Page Six that the multi-hyphenate got TAO Park City “buzzing” with a surprise performance on Saturday night during the Sundance Film Festival.

“She arrived in good spirits and went straight to her table where she danced and sang for the first part of the night.”

We’re told that the DJ spotted the singer, 55, in the crowd and “started engaging with her” by playing her hit song “Jenny from the Block.”

“That’s when most of the crowd realized she was there. She then got up on stage and starting singing along to ‘Jenny’ then performed ‘All I Have,’” the insider adds.

“The energy was buzzing and the Casamigos was flowing. She changed the vibe of the night.”

Both tracks are from Lopez’s 2002 album, “This Is Me… Then,” which was the prequel to her 2024 album, “This Is Me… Now.”

The “Hustlers” star took to her Instagram Story on Saturday to share some snaps from her fun night on the town.

Lopez dressed to impress in a beige track set that consisted a cropped jacket and matching high-waisted trousers.

She also wore gold hoop earrings and brown-hued sunglasses while posing next with her “Unstoppable” co-star Jharrel Jerome.

Another shot showed Lopez holding up an espresso martini while posing in the club. She added her song “Waiting For Tonight” to the snap.

The Grammy-nominated artist is in Park City, Utah, for the Sundance Film Festival premiere of her new film, “Kiss of the Spider Woman,” on Sunday night.

Lopez teased the movie on her IG Stories with her use of spider, spiderweb and red lip emojis on her posts.

On Saturday, J.Lo shared a “sneak peek” at her role in the Bill Condon-directed movie by sharing stills from the film on Instagram.

“💋🕷️🕸️ Lil sneak peek Kiss Of The Spider Woman,” she captioned the post showing her in character as Aurora.

Earlier that day, Lopez also showed off a black all-leather ensemble as she arrived in town to promote her latest project.

“Ready to Sundance ❄️ 💋🕷️🕸️,” Lopez captioned a video taken in the snowy destination.
