Harry Styles throws up onstage?

London: One Direction star Harry Styles left his gig in Pittsburgh to relieve his nausea right in the middle of their song `Rock Me`.

His bandmates - Liam Payne, Zayn Malik, Niall Horan and Louis Tomlinson - continued the performance while Styles, 19, tried to recover after a very `heavy night of drinking` the day before, reported Hollywood life.

After Stles ran offstage, some fans filmed him as he appeared to throw up.

In the video, he was getting down on his knees, wiping his mouth with a towel, and taking a swig of water.

"He went through a period of throwing up before he went on stage. I think he`s over it now though," said Payne when enquired about Styles` health.
