Lady Gaga’s sick of dancing

London: Lady Gaga has been throwing up during performances on her tour because the dance routines are so tough on her body.

The ‘Bad Romance’ hitmaker, 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 to her fans on Twitter.

“Yes Tokyo! Tonight was the first BtwBall that I didn’t puke during show. (yes it’s that hard),” the Sun quoted her as writing.

Last year, Gaga – who has revealed she suffers from stage fright – had to leave the stage between songs after suffering food poisoning.
