Jennifer Lopez's '10-minute performance' at TAO Park City surprises Sundance audience

The multihyphenate, 55, made an appearance onstage with DJ Chase B for the Casamigos event during the annual Sundance Film Festival pop-up, performing two singles from her 2002 album 'This Is Me... Then': 'Jenny from the Block' and 'All I Have'.

According to a source who spoke to PEOPLE, Lopez was in "good spirits" at the end of the two-night event, which took place when she was in town for the premiere of her most recent movie, 'Kiss of the Spider Woman'.

The singer shared several pictures on Instagram from the club where she spent the evening dancing and drinking Casamigos drinks with her best friend, Stevie MacKey, per TMZ.

The source also noted that the "energy was buzzing" and that Lopez's mini-set "changed the vibe of the night." Lopez began the evening dancing and singing from her own table, but she eventually made her way behind the DJ booth and got the audience going.

"I love you guys, thank you so much!" Lopez shouted into the microphone. Lopez, who has 388.7 million followers on social media, also posted a video of herself dancing to her 2005 song 'Get Right'.

Lopez showed off her tense stomach in a beige cropped jacket with puffed sleeves and matching pants selected by styling team Rob Zangardi and Mariel Haenn, per Daily Mail.

The JLo Beauty founder let her hair down with voice coach Mackey, alongside her 'Kiss of the Spider Woman' and 'Unstoppable' so-stars Tonatiuh and Jharrel Jerome.

Jennifer Lopez receives standing ovation at Sundance Film Festival

The 'Atlas' star, wearing a dazzling gown with webbed edges and high black shoes, fought back tears as 'Kiss of the Spider Woman' received a standing ovation at the Sundance Film Festival.

Starring in the musical adaption was a longstanding goal, she told the crowd at Park City's Eccles Theatre. "I’ve been waiting for this moment my whole life," she said.

She added, "The reason I even wanted to be in this business is because my mom would sit me in front of the TV and [‘West Side Story’] would come on once a year."

"I was mesmerized and was like, ‘That’s what I want to do'. This is the first time I actually got to do it. This man made my dream come true," per Variety.

The actress said on Variety's Awards Circuit podcast back in November that the role, based on the 1993 Broadway musical, is "probably the most challenging and rewarding role I’ve ever had."

"It’s about love, acceptance and finding beauty in the darkness. I think those themes are so relevant right now," she said.

Lopez's musical drama 'Kiss of the Spider Woman', directed by Bill Condon, made its Sundance debut on Sunday, January 26.

One said, "She can’t sing …. She should retire for good."

"Go away woman! You’re not popular & you’re desperate to stay in the spotlight," remarked one.
