What goes on in Vegas most certainly will NOT stay in Vegas here!
Watch it go down (below)!!!
Up-chuck the funk, Harry Styles!
The One Direction hottie seemed to be feeling a tad sick during the band's Pittsburgh concert on Monday!
Harry-boo was recorded running behind some set pieces during the middle of Rock Me and appeared to throw up!
Styley was spotted crouching over with a towel and water bottle to help settle his tum-tum, while the rest of the boys continued to perform, covering for their mate!
In the vid, you can see a worried expression from Zayn Malik while attempting to continue with the song!
But no worries!
Louis Tomlinson covered Harry's parts in his absence, and our little 1D lad is A-O-K!
Directioners sending you love and well wishes!
