Justin Bieber Fights Through Vomit, Completes Concert

We already know Justin Bieber is a cutie. But it turns out he's a warrior, as well.

The 17-year old sensation was diagnosed with a chest infection prior to a show in Manila on Wednesday. But did that stop the pop star from completing a 90-minute set? Of course not!

"Justin was advised to either cancel the show or do an abbreviated set," a source told Perez Hilton. "But he insisted on going on. So they cut down the show, but once the show started he kept going."

Yes, depite vomiting "backstage between songs," according to a witness, Bieber would not disappoint fans. It's a testament to his toughness and dedication.
