Justin Bieber has said his fans can expect some "crazy stuff" when he performs at Capital FM's Summertime Ball in London later this year.

The 18-year-old 'Boyfriend' singer is one of eleven artists confirmed to play Wembley Stadium on 9th June.

Speaking to Capitalfm.com, Justin promised an unforgettable show when he takes to the stage, including pyrotechnics.

He said: "Fans can expect some crazy stuff. I'm out there having fun, enjoying myself and dancing. [They'll be] lights and effects and explosives. A lot of stuff."

Justin added that he wasn't nervous about performing at the event for a second time because it came as "second nature" to him.
