Jennifer Lopez Wore a Bedazzled Bikini Top with a Matching Belt Over Her Bare Midriff

Jennifer Lopez's latest look was a nostalgic flashback to the year 2002 — and honestly, not much has changed. She's dating Ben Affleck for a second time, her sculpted abs haven't gone anywhere, and her wardrobe is still just as glam. And last night, the multi-hyphenate harkened back to the early aughts yet again with a performance filled with Y2K trappings at the Rock and Roll Hall of Fame Induction ceremony.

During the event, Lopez sang her 2002 hit "All I Have" alongside inductee LL Cool J, and her outfit was a total throwback. Wearing a bedazzled bikini top underneath a floor-length blue coat straight off the AZ Factory runway, J.Lo paired the combo with black cargo pants and lace-up stiletto boots. She accessorized with a rhinestone-studded belt over her bare midriff, a diamond choker necklace, and her signature hoop earrings.

Her hair was styled slicked-back with two face-framing ponytails on each side.

Following her surprise appearance, Lopez posed for photos backstage and swapped her voluminous jacket for a black blazer. "LOVE IS LIFE AND LIFE IS LIVING !!!! I was honored to be part of something very special for my friend @llcoolj tonight," J.Lo tweeted a photo of herself with the rapper, Eminem, and Dr. Dre.

This fall, Jen's schedule has been jam-packed with work commitments. In addition to her multiple musical performances, she's been shooting her upcoming Netflix thriller, The Mother, in Vancouver, while Ben is filming a movie in Austin, Texas. But despite the distance, the couple continues to "stay connected."

"They are both filming during the week on location, but they have met up whenever possible," a source told E! News. "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."
