Madonna's tenth worldwide tour has just been postponed from late August to September 9th. The "Rebel Heart Tour" is now going to kick off in Montreal instead of Miami. The reasoning behind the reschedule of the already set dates, which moves five shows to January 2016, is lack of time to prepare.

"As my fans already know, the show has to be perfect," Madonna said in a statement, further explaining that the assembling of the elements in the show is going to require more time than what they previously realised. "I apologise for any inconvenience this may cause my fans," she added.

"I can promise you this show will be worth the wait. Can't wait to share it with all my Rebel Hearts out there."

The first two shows in Miami will move from August 2015 to January 2016, as are the Atlanta and San Juan, Puerto Rico concerts. So the opening night will now happen on a Wednesday, September 9th, in Montreal's Bell Centre. The pop star's tour promoter, Live Nation, will honour the tickets already bought for the cancelled shows and will refund consumers if they so ask.

The tour will make a few stops in the UK, beginning in London's O2 Arena on December 1st and 2nd, moving to Manchester Arena on December 14th, then Barclaycard Arena in Birmingham on the 16th, and finishing in Glasgow, at the SSE Hydro, on December 20th.

This hasn't been an easy ride for the Queen of Pop's 13th studio album, Rebel Heart: first, part of its songs in demo stage were leaked online and forced Madonna to a half-release on iTunes, back in December 2014. After it was finally released, in March 2015, stories started to appear stating it was flopping and calling it the worst release for the past 20 years – since 1994's Bedtime Stories.

She also made a series of live performances that sparked either controversy or laughs: in the first weekend of Coachella, she made a surprise appearance during Drake's show and finished with a kiss on the lips that was harshly analysed and criticised. Before that, she took a serious fall while performing "Living for Love" at the Brit Awards, which originated dozens of memes on the internet.

The Rebel Heart album has already produced two hit singles, Living for Love and Ghosttown, which topped the Billboard Dance charts and gave Madonna and unbeatable record – the artist with most Billboard number 1, 45 to be precise.
