Justin Bieber throws tantrum on camera

Singer Justin Bieber blasted the camera crew during his performance on the "Today" show.

The 21-year-old was performing here on Thursday. Bieber started with his new single "What do you mean?" and tried to impress the viewers with his dance moves, but he complained that the cameras didn't capture his dance routine, reports aceshowbiz.com.

After finishing the song, Bieber walked up to one of the cameras and didn't seem to realise that his mic was still on as he ranted: "Next time I won't dance because the camera's here the whole time. I might as well not dance. What do I even do this for if they are just going to do..."

The feed was then cut to show commercials.

Bieber showed off his new platinum hairdo during the morning show.

"You guys like the hair," he asked, to which the crowd cheered in response.

Bieber also delivered "Where are u now" and "Boyfriend" before showing off his vocals in an acoustic version of his claim-fame single "Baby".
