Matt Cardle has reportedly checked himself into rehab.

The 30-year-old singer - who shot to fame after winning 'The X Factor' in 2010 - is said to have signed up for a 28-day programme at The Priory rehabilitation centre in London last night (29.12.13) after allegedly becoming hooked on prescription pills temazepam and Valium.

Friends of the 'When We Collide' hitmaker claim he turned to the drugs after struggling to deal with the stress of releasing his last two albums independently following his split from his record label last year.

A pal told The Sun newspaper: ''Matt is all over the place at the moment.

''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.

''In order to calm himself down he started taking Valium and then temazepam, but things got so bad that he couldn't get up in the morning without taking pills.

''He began to realise he had a problem and decided to do something about it and get clean before his tour.''

Matt is determined to ditch his alleged addiction before kicking off his UK tour next April.
