VIDEO: ONE DIRECTION'S Harry Styles Throws Up On Stage During Concert

It's not the prettiest video, but it is making the viral rounds as ONE DIRECTION's Harry Styles threw up on stage during a July 8th concert in Pittsburgh. The band played on while Styles ... did his thing ... to the side of the stage. Why the upset stomach? Eating a big meal before a show.

One Direction includes Niall Horan, Zayn Malik, Liam Payne, Harry Styles, and Louis Tomlinson. The members of One Direction all auditioned for the UK edition of Cowell's hit international reality singing competition, THE X FACTOR, and were hand-picked by the impressario to become the new boyband to take over the world, just as his own Westlife had before them. The rest, they say, is history - over 14 million singles and 8 albums sold in three short years
