The theft allegedly occurred following Madonna's guest appearance during Sabrina Carpenter's headlining set, where they performed a medley of hits.

The 67-year-old star expressed her heartbreak on social media, noting that the pieces are irreplaceable.

Security at the festival is under review after reports of several other high-profile thefts during the second weekend.

Madonna's team is working with local authorities to track down the missing wardrobe, which includes iconic pieces from her 1990s era.
