Tonight’s Billboard Music Awards ended with a special tribute to Prince, performed by the late icon’s close friend, Madonna.

After a beautiful introduction and tribute read by Questlove, the Queen of Pop performed a moving rendition of “Nothing Compares 2 U” wearing a purple Prince-inspired look while sitting on a purple throne chair. She was later joined on stage by Stevie Wonder for an emotional duet of “Purple Rain.”

At the end of their performance, Madonna thanked Stevie Wonder and then concluded the evening by thanking Prince, “Most of all, thank you, Prince Rogers Nelson, for all that you have given us.”
