Madonna Keeps Concert-Goers Waiting More Than 3 Hours in Miami

The Material Girl angered fans on the final two dates of the North American leg of her MDNA tour.

Madonna's concerts in Miami this week left some fans grumbling.

Marking the final two dates on the North American leg of her MDNA tour -- projected to be one of the highest-grossing tours of all time -- Madge hit the stage Monday at the American Airlines Arena a whopping three and a half hours after its scheduled start time. Her opening act, DJ Paul Oakenfold, finished his set at 10 p.m. -- two hours after the 8 p.m. kickoff -- but Madonna didn't appear until 11:30 p.m., according to the Miami Herald. Many in the Twitter-verse, including Miami native and gossip blogger Perez Hilton, had complaints about the wait, while some expressed worry over the singer's unusual tardiness. Typically, Madonna has been hitting the stage between 10 and 10:30 p.m. during previous shows on the tour.

Officials for the MDNA tour blamed technical problems for the delay but promised fans that the second Miami show on Tuesday would start on time.

Alas, Madonna began her Tuesday performance at 11 p.m., Vintage Vinyl News reports. Amid boos from the crowd, the singer reportedly offered no explanation for why she was late. Many audience members exited the venue before her performance even began, and some demanded refunds.

A rep for Madonna did not immediately answer The Hollywood Reporter's request for comment.

The MDNA tour, while raking in huge grosses, has been plagued with bad press. The Material Girl upset Colorado concert-goers last month with the use of a prop gun in the wake of the Aurora tragedy and faced criticism overseas by superimposing a swastika over an image of right-wing politician Marine Le Pen, among other missteps.

The iconic pop star certainly is no stranger to controversy, but while sales of her MDNA album have been subpar, the tour has proved to be a prosperous endeavor. As of Nov. 21, the MDNA world tour has grossed nearly $233 million, according to Billboard's Boxscore.

After Thanksgiving, Madonna will continue on her worldwide trek to South America. She kicks off the final leg of the tour in Mexico City on Nov. 24 and takes her final bow on Dec. 22 in Cordoba.
