Jennifer Lopez took a trip back to the early ’00s for a throwback performance.

The pop star made a surprise appearance at the 2021 Rock and Roll Hall of Fame Induction in Cleveland, Ohio, last night, where she joined inductee LL Cool J to perform their 2002 hit “All I Have.” Lopez wore a shining look, styled by Rob Zangardi and Mariel Haenn, featuring a sequined bikini top, layered Dolce & Gabanna belts, black cargo pants, and sparkly stilleto boots from her own DSW collection.

In pics from the performance, the “Jenny from the Block” singer also donned a royal blue floor-length jacket straight off the runway, from the AZ Factory tribute show in Paris, which honored the late designer Alber Elbaz.

Lopez has a jam-packed schedule this fall, as she shoots her upcoming Netflix thriller, The Mother, in Vancouver. Her work takes her away from her boyfriend Ben Affleck, who’s also filming in Austin. According to an insider, the couple has stayed connected during their brief long-distance run, and meeting up often on weekends.

“They are both filming during the week on location, but they have met up whenever possible,” the source said. “They are working out their schedules so that they can be sure to see each other every few days. Things are good between them, and they are staying connected. They are busy with their projects, but also making time to be together.”
