The 'Purple Rain' hitmaker played a special late-night gig for just 33 fans and the 'Music' singer and her backing dancers, who headed over after her concert at Minneapolis' Xcel Energy Center.
Madonna took a place at the front row of the intimate show and gazed "adoringly" at the singer.
Andrea Swensson revealed in a blog for local radio station the Current: "I had expected her to hang back a bit, or maybe be sitting in her roped-off area, but once I stepped a little closer to the stage I realised that she was not only in the front row, but had perched on the edge of the stage at Prince's feet, looking up at him adoringly as he sang.
"There is a face that people make when they are watching Prince play guitar; it's a gleeful expression that combines the joy of going down a roller coaster with the realisation that you are witnessing a moment that might never be recreated by another being that lives on this beautiful Earth. It turns out Madonna also makes that face when she is watching Prince play."
And according to the onlooker, the 'Little Red Corvette' hitmaker was "nervous" in front of his star guest.
She added: "Prince, too, seemed a little awestruck by Madge, appearing nervous as he flitted around the stage to different instruments and taking great care to get the lighting, sound, and chord changes just right."
But Madonna didn't stay for the whole show, which also saw Prince invite fans on stage to sing and dance along with him.
Andrea added: "After the sixth song of the set, Prince leaned down and whispered something back and forth with Madonna, and then hopped back up to his keyboards and simply said, 'Cool.'
"With that, Madonna made her way out of the building and Prince was left alone with his band and small group of adoring fans."
