Promoter Everything Is New issued a statement on Facebook apologizing to fans and thanking them for the 'well-wishes for Madonna’s recovery'.
'We sincerely regret the disappointment to fans due to the unforeseen and last-minute changes to the schedule,' it said.
Wednesday evening’s concert was the second show the star has canceled since kicking off her European tour in Lisbon on Jan. 12, where she has lived since mid-2017.
'Sorry I had to cancel tonight,' the 61-year-old wrote on Instagram after the first cancellation in Lisbon’s Coliseu dos Recreios venue on Sunday. 'But I must listen to my body and rest!'
According to the promoter, Madonna’s final show of the initially scheduled eight in Lisbon on Thursday is expected to go on as scheduled.
