• Jennifer Lopez performed at Vax Live, a COVID-19 vaccine concert organized by Global Citizen.

Jennifer Lopez serenaded her mother in a sentimental performance during Global Citizen's "Vax Live: The Concert to Reunite the World."

Fully vaccinated music fans and frontline workers joined together on Saturday at Inglewood's SoFi Stadium for the star-studded event. The global broadcast was hosted by Selena Gomez, while Prince Harry and Meghan Markle, the Duke and Duchess of Sussex, served as campaign chairs.

The opening number was performed by Lopez, who wore a dazzling jumpsuit as she sang a live cover of Neil Diamond's "Sweet Caroline" in tribute to her mother, Guadalupe Rodríguez.

"When I was thinking about what song to sing tonight, I remembered the song she always used to sing to me when I was a baby," said Lopez, 51. "So if you would indulge me, I'd love to sing that one tonight."

The "On the Floor" singer told the crowd she didn't spend Christmas with her mother for the first time last year due to the COVID-19 pandemic.

"We've been away too long, but she's here with me tonight, and she is vaccinated," Lopez said.

Midway through the performance, Lopez instructed her band to pause briefly and ran to pull her mother onstage for a special moment.

Rodríguez revealed that she used to sing "Sweet Caroline" to rock Lopez asleep but instead changed the lyrics to "Sweet Jennifer."

Lopez also performed her 2016 anthem "Ain't Your Mama" before other artists like Foo Fighters, J Balvin, and H.E.R. took the stage.

Ahead of the concert, the two women posed together in sweet photographs alongside Lopez's 13-year-old daughter Emme. The Instagram photos were shared on Friday as part of Lopez's beauty brand, JLO Beauty.

"Three generations, but one belief - WE ARE LIMITLESS (and so are YOU!)," the photo was captioned. Lopez later shared a behind-the-scenes video from the photoshoot and an additional picture of the three together for Mother's Day.
