George Michael was reportedly fined $260,000 (GBP130,000) after his opening concert at the new Wembley Stadium in London overran by 13 minutes.
The singer was the first artist to perform at the renovated venue - but walked away with a hefty charge for performing for too long.
A source says, "Wembley has strict rules that gigs must finish at an agreed time or face a GBP10,000 fine for each minute they continue. George slipped two extra songs into his set and racked up a huge bill. He was enjoying himself so much he didn't care."
A Wembley spokesperson said, "Wembley can issue fines for concerts that overrun, but that's between Wembley and the concert promoters."
