One Direction heartthrob Harry Styles became seriously ill during a recent concert.

The 19-year-old star fell ill during the band's tour stop in Pittsburgh on Monday. Styles was seen performing along with the rest of his bandmates when he suddenly ran behind a set piece, hunched over, and vomited.

Harry was seen clutching a towel and a water bottle while the rest of the boys continued to perform, covering what would have been Harry's solo parts in the song. Harry has yet to comment on the incident, but reportedly the pop stars had spent the night before partying up all night.

The boy band will continue to play their sold out world tour through the Fall of 2013. We all know that they have to “live while they're young,” but with their busy schedule: the boys should really focus on taking care of themselves a little better!
