Chubby Pete's new addiction sees him piles on the pounds

The reformed drug addict looked positively tubby as he emerged from a north London pub after meeting up with his bandmates.

Wearing a black suit and his trademark brown trilby, the singer's white shirt appeared to be straining against his greatly increased girth which seems to have expanded after spending a month in rehab to kick his addiction to drugs.

Clearly, Pete rediscovered his appetite for all things edible during his stay at the Clouds Clinic as the once waif-like Doherty looked much rounder in his face, but healthier than he has for some time.

Following his release from rehab, the singer, who is rumoured to be engaged to model girlfriend Irina Lazareanu, has been forced to take up residence outside London as part of his bail conditions.

He's opted to move into a cottage in the quaint Wiltshire town of Marlborough to avoid London – and his druggy pals.

But the singer whose tempestuous relationship with Kate Moss finally imploded three months ago appears to be settling in quite well.

Locals were thrilled when he turned up at local pub the Sun Inn.

An onlooker said: "It was a normal Saturday night until Pete rocked up.

"As soon as word got out, the place was packed and people were begging him to sing.

The source told The Sun: "He was asking for pints of Guinness as he paused between the tracks and was kissing all the girls who asked for one.

"It was a really great atmosphere."

Pete's band Babyshambles went to No5 in the album charts yesterday with Shotter's Nation.
