Washington, Jun 21 (ANI): English singer George Michael stunned his fans, who attended his first U.S. concert in 17 years - by going commando onstage.

Fans who made it to the San Diego, California show on June 17, revealed that they could make out that the Faith singer was not wearing any underwear.

“You could tell he wasn’t wearing underwear. It (his penis) was flopping all over the place,” Contactmusic quoted a concert-goer as telling E! Online.com.

Besides the added thrill to his fans, the concert is said to have gone on very well.

“Everything from his voice, to the lighting, to the stage was beyond anything I have ever experienced,” the concert-goer added. (ANI)
