Simon Cowell wants to quit smoking

The 52-year-old has reportedly started treatment at an addiction clinic to finally put an end to his 15-plus a day habit.

'Simon has made it his New Year Resolution,' an insider reportedly revealed.

'Simon’s mother and some of his closest friends have been nagging him for some time about trying to stop smoking. His grandfather Robert was a heavy smoker who died of lung cancer. His father suffered a heart attack.

'It’s made Simon think long and hard about his own health now.'

The music mogul is believed to have smoked since he was a teen, but now wants to bring an end to his most unhealthy habit.
