BRAD Pitt has revealed details of a dodgy love affair and come clean on why he’s sporting a scraggly beard.

At the afterparty for his new movie, Kick-Ass, Pitt was asked why he was cultivating the facial hair – deemed by many to interfere with his rugged good looks.

“It’s boredom. No other reason than that,” he answered, drinking a pint of Guinness and smoking a cigarette.

Angelina Jolie’s other half spoke also revealed that he had once been run out of a UK town for getting together with the wrong girl.

Pitt, 47, said that before he was famous he went on a tour of Scotland. “I went everywhere, saw it all. Edinburgh and Glasgow were special. I even went up to Loch Ness to see what that was all about.

“When I was in Glasgow I got involved with this girl. She happened to be the ex-girlfriend of a bit of a bad guy.

“I ended up having to get out of town because I was getting ‘that’ look from a guy behind a bar.

“I think there is something about rival gangs in the city and I was about to find I was involved. I had to get out of there. It was heavy.”
