The 'Contraband' actor - who already has one Wahlburger restaurant in Hingham, Massachusetts - admits business is going so well he is now expanding it to the other side of the Atlantic Ocean.

He said: "We do higher-end burgers. Yesterday, we sold 1,300. It's run by my brother, Paul, who is a five-star chef. We're opening a bunch of them in Britain and Ireland this year."

The 40-year-old hunk admits many people did not think it would work when he first conceived the idea but is finding it has done surprisingly well, currently making $17,000 a day.

He added to the Metro newspaper: "When I first mentioned the idea of Wahlburgers, people were like, 'Oh my God, that's a stupid idea.'

"What they don't realise is how talented my brother is. I would never risk putting my name out there in a way that would end up being bad. You can get people to show up because of the name but they are going to come back because they like the food.

"A successful burger place takes maybe $2,400 a day. A really successful one does $6,000. We're making $17,000 a day. There are lines queuing around the corner."
