Eurovision 2019: Madonna blasted for being 'out of tune' during controversial performance

Pop queen Madonna was blasted for being "out of tune" during her incredibly controversial performance on Eurovision tonight.

Her much-anticipated appearance, which had not been seen by commentators, was met with bemusement as she failed to hit the right note.

The diva, 60, performed her 1989 hit Like A Prayer and her new single Future with US rapper Quavo.

Her first performance of Like A Prayer saw her walk down the stairs in a church robe.

Organisers of the contest said earlier this week that the pop diva had not yet signed a contract and that she could not perform without one.

However she was spotted arriving in Israel on Tuesday and was rumoured to be rehearsing in a secret location.

Madonna will be performed two songs in the interval during tonight's final - her 1989 hit Like A Prayer and her new single Future with US rapper Quavo.

The star hit Tel Aviv, Israel, with a crew including 25 dancers, 40 backing singers, a director, a choreographer and animators.

And her kit has piled extra pressure on stagehands, with one source saying: “They have enough work as it is with the 41 acts and now she’s adding 30 tonnes of props too.”

Madonna singing Like a Prayer, to mark her hit’s 30th anniversary, could prove controversial.

An insider said: “A song about religious devotion sung in this part of the world, at this time, could be quite incendiary.”
