Los Angeles, California - Pop superstar Madonna is appealing for the return of missing costumes she wore during her recent Coachella set with Sabrina Carpenter.

The Like A Virgin singer (67) took to Instagram to ask for help in finding outfits that vanished after the show.

"I discovered that the vintage pieces that I wore went missing – my costume that was pulled from my personal archives – jacket, corset, dress, and other garments," the diva wrote.

"These aren't just clothes, they are part of my history," she said, adding that other items from the same era had also gone.

The missive came after her viral appearance alongside Carpenter (26) during Friday night's headline set at the festival's second weekend in the California desert.

The duo performed Madonna's 1990 hit Vogue and 1989's Like A Prayer – chart smashes around the world a decade before Carpenter was born.

"I'm hoping and praying that some kind soul will find these items and reach out," Madonna said, adding: "I'm offering a reward for their safe return."

The Espresso artist amplified Madonna's pleas by resharing the message to her more than 50 million Instagram followers in the hopes of tracking them down.
