Justin Bieber's surprise appearance at a fashion show did not go as planned as the singer, who decided to strip down to his boxers, got booed in the process.
Bieber, who has been in news for his trouble with the law, took to stage with supermodel Lara Stone at CBS's 'Fashion Rocks' event to present performer Rita Ora and the Calvin Klein fashion show.
The singer's appearance was met with equal amount of approving shrieks and jeers which continued as he started shedding his blue blazer, jeans and T-shirt to promote the brand.
Bieber's fans, however, manage to drown the jeering with their shouts of encouragement to the singer.
"Grandma always said kill 'em with kindness... And then strip on live national TV. Lol," Bieber, 20, later tweeted.
