Have you secretly always wanted to kick Justin Bieber's ass? Have you openly always wanted to kick his ass? We haven't, because we love the kid, but we suspect there are people who might wanna see him get beat up!

Luckily for them, Complex magazine got Bieber in the gym with a professional boxer for their 10th anniversary, and he just brutalized the kid. I can't believe anyone around Justin Bieber would allow this, because his very lucrative face may never look the same, but they did, so check out the video at Complex.
