Madonna surprised her fans

London: Pop star Madonna surprised her fans when she made an appearance at the Ultra Music Festival in Miami, Florida to introduce her producer, Avicii. The pop superstar made her debut at the annual event on Saturday after a clip from the festival`s new film "Can You Feel It" was played to the crowd, reports a website.

The crowd was stunned when she stepped out from the darkness and into the spotlight to join Swedish house producer-DJ Avicii onstage.

"Hello, everybody, I`ve finally made it to Ultra Music Festival! I`ve been here in spirit for many years, but it`s good to be here, finally," she said addressing the audience.

"In my world, music and dance are not separate. Electronic music has been a part of my career since I started, and I can honestly say, a DJ saved my life," she added.

Then she presented Avicii to the masses.
