When British-Irish boy band phenomenon The Wanted played Fuse's studios on Wednesday, April 25, our building was swarmed by throngs of uber-psyched fans. Things were just as crazy backstage, from Jay hitting Siva in the jugular with a grape to a flying middle finger. 

Our cameras followed The Wanted before and after their live performance and caught these hilarious, candid moments. You can either watch the video above to witness The Wanted's backstage antics in their entirety or skip ahead to the cue times given below to catch the highlights.
