Stepping out to support his friend, Justin Bieber  stopped by Lil Twist's "Closer to My Dreams" tour at the House of Blues in Anaheim for a surprise performance last night (July 10).
The 17-year-old sensation hopped onstage with the Young Money rapper, inciting all sorts of teenage pandemonium before churning up the excitement even more with a revamped rendition of "Wind It."

Offering up an explanation for the mid-concert collaboration, Justin tweeted, “#supportyourfriends #SWAG."
