Justin Bieber bloodied and beaten up after a few rounds in the boxing ring

He is the diminutive teenage pop star, known for his baby face and innocent lyrics that have made him a household name. But in a new photo shoot, Justin Bieber will no doubt shock fans with this bloodied, beaten up and tough guy appearance.

The 18-year-old Baby singer is seen drenched in blood as he's punched in the face by a burly boxer.

The image is just once of many incredible shots taken by world-renowned fashion photographer Tony Kelly for a stunning new photo shoot for Complex magazine.

Dressed in a ring master style outfit with a white tuxedo shirt and black bow tie, Bieber is seen being hit hard in the jaw and subsequently spits out a mouthful of blood.

His shirt ripped and his face heavily bruised and bloodied, the teenager is held back by a bikini-clad ring girl as he readies himself to fight back.
