Teen superstar Justin Bieber is donating his famous locks to charity after undergoing a makeover.
The Baby hit-maker is known for his carefully preened hairstyle but he shocked fans by having a trim on Monday, opting for a more "mature look".
He immediately showed off his new image by recording a new music video with Rascal Flatts - and the band's Jay DeMarcus posted a photo of Bieber and himself on Twitter.com, showing the singer's new hairdo.
And the star is using his image overhaul to raise cash for charity - in a post on his own Twitter page, he writes, "Yeah so it's true... I got a little haircut... I like it... and we are giving all the hair cut to CHARITY to auction. Details coming soon."
