Poor Harry. All that partying is clearly taking its toll.

Harry Styles threw up during a One Direction concert on Monday, and while it wasn't as glorious a spectacle as when Bieber did it, it's still worth watching.

The party boy was spotted grabbing his stomach and running off stage at the end of the group's performance of 'Teenage Dirtbag' and missed the entire next song 'Rock Me', while his bandmates - Niall Horan, Liam Payne, Louis Tomlinson and Zayn Malik looked around panicked but successfully covered his solo at the gig in Pittsburgh, Pennsylvania, which we're sure will go down in memory for Harry at least.

Styles wasn't the only one suffering that day, as Liam tweeted in the morning:


According to RadarOnline, user amadak822 posted on YouTube: 'I was there! He got dehydrated and overheated and ended up throwing up backstage. :( He missed Rock Me but came back right after and said, 'Sorry bout that! (sic)' '

Fingers crossed he made it to a bucket or something and not onto an unfortunate roadie. Although there are probably some One Directioners out there who'd pay for an experience like that.
