Madonna gave a noticed performance during the Eurovision final on Saturday.
The pop star is marking the release of her forthcoming album Madame X with her guest performance, which came after all the contestants had had their turn onstage, during the voting period.
She opened her short show with "Like A Prayer", for which she was accompanied by a choir, reviving her 1989 hit.
The second half of her performance consisted in the reggae-inspired song "Future", sung in a duo with Quavo.
Madonna chatted with one of the Eurovision hosts shortly before her turn onstage, at one point quoting her own tune "Music" and getting the crowd to repeat her lyrics: "Music makes the people come together".
Madonna also addressed a pep talk to the contestants, telling them: "You're all winners, no matter what happens. Because to get here was not easy.
"You had to have a dream, and believe in that dream, make a lot of sacrifices to get here, and that, in my opinion, makes a winner."
The singer had faced calls from a Palestinian-led campaign to avoid performing at the event in Israel.
But the Queen of Pop rejected the boycott motions, saying she will "never stop playing music to suit someone's political agenda".
Her performance appeared to fail to convince viewers, several of whom thought the singer sounded out of tune.
