YOU wouldn’t want to be at the side of the stage for one of Lady Gaga’s gigs. The singer has been throwing up during performances on tour because the dance routines are so tough on her body. Gaga, who kicked off her Born This Way Ball tour in South Korea last month, had her sixth show in Tokyo, Japan. She revealed just how tough the performances had been, telling fans on Twitter: “Yes Tokyo! Tonight was the first BtwBall that I didn’t puke during show. (yes it’s that hard).” Last year, Gaga – who has revealed she suffers from stage fright – had to leave the stage between songs after suffering food poisoning. The stage hands must be getting paid extra.
