Jennifer Lopez stepped out in a skin-baring crop top after debuting her apparent Ben Affleck revenge song, “Wreckage of You.”

In photos obtained by Page Six Saturday, the pop icon donned the crisp white long-sleeved top in Malaga, Spain, before performing there that evening.

She showed off her flawless abs in the eye-catching crop top, which she wore with several buttons undone to show off her layered gold necklaces — including a body chain and a nameplate pendant. Her extended sleeves appeared to feature arm-length flaps and a cut-out back.

The “Jenny From the Block” singer paired the look with wide-legged beige pants and topped off the skin-baring look with a navy blue ball cap sporting her first initial. Lopez carried a black crocodile leather bag and donned aviator sunglasses for the sunny outing.

The “Waiting for Tonight” songstress launched her Up All Night Tour in Pontevedra, Spain, on Tuesday, and has since rocked crowds in Malaga and Cadiz.

The “Kiss of the Spider Woman” actress, 55, seemingly reflected on her brief marriage to Affleck in “Wreckage of You” — a song she debuted during a Los Angeles listening party on July 2.

“’Wreckage of You’ is a pop ballad that she told us she cowrote and recorded two weeks ago,” guest Edgardo Luis Rivera told Us Weekly.

“She said she was lying in bed after a long day of tour rehearsals when the idea of the song came to her,” he continued.

“She mentioned how last year was a very difficult time for her both personally and professionally. She had to cancel her tour and really focus on herself. Fast-forward to one year later, and she feels better and stronger than ever, so she wanted to write a song about coming out of a bad situation much stronger.”

She “kept thinking of the word ‘wreck’ because it means destruction, but she wasn’t destroyed,” Rivera explained to the outlet. “In fact, the lyrics of the song are, ‘I’m stronger after the wreckage of you.’”

Lopez’s ex — from whom she settled her divorce after two years of marriage in January — was spotted sitting front row at the Red Sox game on Friday with his first ex-wife, Jennifer Garner, and their kids Seraphina and Samuel.

The exes have an exceptionally warm co-parenting relationship — and one that seemingly hasn’t been easy on the “Accountant” star’s second ex-wife.

A source told Page Six in March that Lopez was “not happy with constantly seeing photos” of Affleck with Garner.

A source said that seeing pics of the former couple — including a snap of him wrapping his arms around Garner during a paintball outing for son Samuel’s 13th birthday — was like pouring “salt in the wound.”

Affleck and Garner share kids Samuel, 13, Seraphina, 16, and Violet, 19. They split in 2015 after ten years of marriage and finalized their divorce in 2018. Lopez and Affleck — who were previously engaged in 2002 — married in 2022 after rekindling their romance in 2021.

Garner is currently dating John Miller, whom she was seen making out with in front of his Los Angeles house in June.
