Two Madonna fans are suing the US singer for being late by more than two hours for a show last month in New York, according to court documents.
They state the show was meant to start at 20:30 EST on all three nights, but in each case it did not begin until after 22:30, ending around 01:00.
The case says they “would not have paid for tickets” had they known it would finish so late.
The BBC has asked Madonna, Live Nation and the Barclays Center for comment.
The case, brought by Michael Fellows and Jonathan Hadden, states that “many ticketholders who attended concerts on a weeknight had to get up early to go to work and/or take care of their family responsibilities the next day”.
They are suing promoter Live Nation and venue the Barclays Center for “false advertising, negligent misrepresentation, and unfair and deceptive trade practices”.
Mr Fellows and Mr Hadden attended the show on Wednesday 13 December 2023, but the legal documents note that other nights at the same venue, on 14 and 16 December, also reportedly started more than two hours late.
“Defendants failed to provide any notice to the ticketholders that the concerts would start much later than the start time printed on the ticket and as advertised, which resulted in the ticketholders waiting for hours,” the document state.
