Justin Bieber Gets A New Hair Cut

Justin Bieber has unveiled a new hair cut.

The 17-year-old singer debuted his new spikey quiff during an appearance on US talk show, The Tonight Show with Jay Leno.

It is the second time the 'Mistletoe' star has had a radical new hair cut since he first emerged in 2009 with his famous trademark curtains.

Justin spoke about his new Christmas album 'Under The Mistletoe' during the interview, including his collaboration with Mariah Carey.

"Mariah Carey, she's super cool, It was cool because I got to do 'All I Want To For Christmas is You'," he said.

But Justin also admitted that he and Mariah had some difficult moments in the studio.

"It was tricky," he said. "She has super high notes, and it wasn't like she was going to change the key for me, so I had to go in and do her key."

'Under The Mistletoe', which was released this week, also features collaborations with Usher and Boyz II Men.
