Justin Bieber proved he is a good sport by taking to the stage at a Los Angeles comedy club to be 'roasted' by funnyman Chris D'elia.
The teen pop star was in the audience at the Laugh Factory on Friday (13Dec13) when the Whitney star ordered him to take a seat in front of the stunned crowd.
D'Elia then went on to mock Bieber's wardrobe, joking, "I brought Justin up here because his outfit is the most ridiculous f**king outfit I've seen in my life. What is this? A leather tank top?
"Also people lose their lives for watches like that. I like the way he (Bieber) is looking at me like, 'It's just swag, motherf**ker'."
The Baby hitmaker laughed throughout the set, before racing off the stage once D'Elia's routine was over.
