Among Avicii's fans packing the Ultra Music Festival on Saturday (3/24) at Miami's Bayfront Park was none other than Madonna.
During a pre-recorded segment where Avicii praised Madonna for her use of EDM beats over the years, the Material Girl herself walked right to center stage and greeted the crowd. "Electronic music has been a part of my career since I started, and I can honestly say, 'A DJ saved my life'," Madonna told the crowd, according MTV News. When it came time to make the official introduction she exclaimed, "This next DJ is amazing! Get ready for Avicii!," after which the pair laughed and rocked out together to Madonna's new single "Girl Gone Wild."
