Justin Bieber's bizarre Grammys performance in BOXERS baffles fans as he returns to the stage: 'Why is he naked?'

Justin Bieber was back with a bang to perform at this year's Grammys, but many fans were stunned when he came out on stage wearing nothing.

The 'Baby' Singer delivered one of the most talked about performances for the evening, wearing nothing but a pair of silk boxers and socks, with no shirt and a guitar in one hand.

The star's stripped-down rendition of his hit song 'Yukon' from the recent album Swag marked a major return to the stage for a Grammy live performance in so many years.

While fans were glad to see him there, many questioned time and time again why he was naked in front of the world.

While some did express amusement, the majority called it just bizarre and confusing. The performance came during a night when Bieber was nominated in four major categories, including Album of the Year and Best R&B Performance, but he did not win any accolades that evening. Cameras were also seen capturing his wife and supermodel Hailey Bieber in the audiencec who watched her husband perform proudly on stage.
