Rocker Pete Doherty has sparked rumours he's checked into rehab early after cancelling a concert in his native U.K.
The Libertines frontman was booked to play a show in Somerset, England on Wednesday (18Apr12) but the gig was axed on Tuesday (17Apr12).
No reason was given for the cancellation, but it sparked fears the musician, who has battled a drug addiction for almost 10 years, has checked into a clinic after he revealed last week (beg09Apr12) he was due to receive treatment later this month (Apr12).
