British singer Matt Cardle has hit headlines in the U.K. amid unconfirmed reports suggesting he has checked into rehab.

A story published in Britain's The Sun newspaper suggests The X Factor U.K.'s 2010 winner checked into London's The Priory Clinic on Sunday (29Dec13) to seek professional help for a prescription drug problem.

A source tells the publication, "His last two albums have done well in the charts, but the amount of work he has had to put in has been unreal, and it all started to get too much for him... He began to realise he had a problem and decided to do something about it and get clean before his tour."

Cardle, who released his last two albums, The Fire and Porcelain, independently after parting ways with Columbia Records in 2012, is set to go on tour in the U.K. in April (14).

A representative for the star had yet to respond to a request for comment as Wenn went to press.
