Madonna has been fined £135,734 (€170,951) by Wembley Stadium officials for breaking the venue's curfew during the London stop of her Sticky & Sweet world tour earlier this month.
The show overran the 10.30pm curfew by 40 minutes when she played there on September 11 - her only date in the UK.
And she has now been charged £50,000 (€62,972) for every 15 minutes she overstayed her welcome.
A Wembley Stadium source says: "The concert was meant to start at 8.30pm but Madonna didn't come on stage until 9.10pm. The gig ended at 11.10pm so she was quite a bit over.
"Her people knew about the possible implications for going over the curfew but this is a pretty hefty fine, even for Madonna."
