The jewelry was being transported by plane by the woman, instructed to deliver the expensive gems to the 28-year-old singer, when it was left on the plane inside the courier’s luggage, according to AFP.

Police sources in France told AFP the woman, who remains anonymous, was on a flight from London Luton Airport to Nice on May 16 when she left her coat and luggage — which held the jewelry — on the plane when she got off.
By the time the woman realized she didn’t have the jewelry loaned by a luxury brand, the plane had already taken off for a return flight to Luton.
The jewelry was recovered at Luton and sent back to Nice by London’s Heathrow Airport.
