The British singer - who spent time in jail last year after crashing his car into a shop window while under the influence of drugs – is said to have decided to turn his life around for once and for all.
A source told The Mirror the Careless Whispers star has even ditched cannabis.
“George has cleaned up his lifestyle pretty dramatically and stopped smoking the wacky baccy,” said the insider. “He blamed this for giving him uncontrollable hunger pangs and he is now eating in far greater moderation. George has lost almost a stone and a half. He looks fantastic – like the old ... well, young ... George.”
And taking to Twitter, George told his fans about his new, sensible lifestyle. “Hey everyone, had to go out and celebrate in Old Compton St. Had a blast ... had two glasses of wine, danced my arse off. But was sensible enough to be home by 2.30!”
