Swagger: Justin Bieber leaves a clothes store in Sunset Plaza, Los Angeles, yesterday wearing a crude blue T-shirt
He burst onto the music scene two years ago as a cutesy, clean-cut pop sensation.
But it would seem Justin Bieber is becoming quite the rebel these days.
The 17-year-old star was spotted yesterday wearing a T-shirt which quite literally turned the air blue with an unmissable, unsavoury song lyric printed in huge white writing.
Carry my bags: The 17-year-old got a minder to hold his purchases from the Armani Exchange
The line is taken from the original version of the Cee Lo Green track, Forget You, and read: 'F*** you and f*** her too.'
With some swagger in his step, the cocksure singer strode out of the Armani Exchange shop in Sunset Plaza, Los Angeles, where he had just purchased some new clothes.
No doubt the parents of his many legions of young fans would not be too impressed with Bieber's choice of attire.
I'm not a kid any more: Justin teamed his look with a matching blue cap, shorts and trainers
With the singer set to celebrate his 18th birthday next year, it seems Bieber taking strides away from his childlike image.
He has an older girlfriend in the form of 19-year-old Selena Gomez and has also been topping up his tattoos recently - bringing his total to three.
The star has just returned from Miami, where he joined his Gomez on her Dream Out Loud tour.
On a break: The singer is taking a month off before getting back into the studio
Bieber was also spending time with singer Sean Kingston, who recently recovered from a jetski accident.
Bieber describes the star as a 'real friend.'
He is taking a month off to relax with his pals - and of course Selena - before beginning work on his next album.
