PHOTOS: Justin Bieber & Usher Perform On Today Show As Teenager Confirms DNA Test

Usher joined his young protege Justin Bieber on the Today show this morning to perform a special set. 

The teenager - looking festive in a red jumper - looked happy to be joined on stage by the man who launched his singing career. Biebs performed tracks from his latest release, Christmas album Under The Mistletoe but kicked off the set with hit single 'Never Say Never.'

Justin then brought out his BFF Usher who struck a series of poses and waved at the screaming audience.

Meanwhile, Justin made an appearance on The Late Show With David Letterman, where he confirmed that he had taken a DNA test. "Yeah, I took it ... They just swab your mouth," he told David before making a joke about his baby accuser Mariah Yeater, saying: "I could smell a weasel, too!"
