The 'As Long As You Love Me' singer performed outside the NBC show for fans gathered to see him.

Justin Bieber treated fans to an impromptu acoustic performance of 'Boyfriend' following his appearance on The Tonight Show With Jay Leno yesterday (27th June).

The 'All Around The World' star had arrived at the Los Angeles studio ready for his interview and performance with host Jay Leno on this week's show, but parked up his customised Mercedes Benz minivan after spotting several fans in the car park.

Justin, who was decked out in a denim and leather jacket, spoke with fans before surprising them with a live performance of 'Boyfriend', backed by his guitarist and musical director Dan Kanter.

"After we filmed we played acoustic for all the fans waiting outside the NBC gates. Great to see how much JB appreciates his fans," Dan tweeted after the event, before Justin himself added: "Heck yes. played for them. #withdankanter."
