In a development that has left the fashion police and the actual police mildly bemused, Madonna has announced a reward for the return of several vintage costume pieces that went missing after her Coachella performance last weekend. The Queen of Pop took to Instagram to clarify that these are not mere garments, but artifacts of her personal history, which presumably makes them priceless, or at least worth a reward.

Among the missing items are the specific purple jacket, corset, and dress she wore during her surprise guest appearance with Sabrina Carpenter at the California festival on Friday night. Madonna expressed hope that a "kind soul" would find them, adding the pragmatic incentive of a cash reward for their safe return. The sentiment is heightened by the fact that she wore the same boots, corset, and jacket during her Coachella performance two decades ago, creating what she described to the crowd as a "full-circle moment." Several other items from her personal archive "from the same era" have also vanished.

According to the Indio Police Department, who spoke to TMZ, the clothes were last seen on a golf cart on the festival grounds at 01:30 local time on Saturday. A police spokesperson offered the reassuring theory that there is "no evidence to suggest the bags were intentionally stolen," and they may have simply fallen off the cart en route to being loaded onto a bus. The BBC has contacted the department for further comment, presumably to ask if they've checked under the seats.

During the performance itself, Madonna and Carpenter sang duets of 'Vogue' and 'Like A Prayer.' Madonna also debuted a song from her forthcoming album 'Confessions II,' a sequel to 2005's 'Confessions On A Dancefloor,' which is scheduled for release in July.
