Fans of the Canadian superstar Justin Bieber were recently pranked in Boston when a lookalike walked around the heartthrob's concert venue dressed as him for a joke.

16-year-old Jeremy Frost joined forces with his Three Amigos Comedy co-stars Jimmy Lawrenson and older brother Zack for the elaborate outing and explained to Mashable that pretending to be the sensation in Boston on the same day as his concert was too good to pass up:

"The initial response was great when we walked out for the first time. Luckily, we had a couple of people with us to hold some of the girls back. Then, when we went inside, people continued to take pictures and put them on Twitter."

"Originally, we were just going to do it in a mall or something, but then we found out he was going to have a concert in Boston in July. So we put it off for a couple months. His fans are the most dedicated in the world and we knew that if they even saw a glimpse of him, they'd freak out. We couldn't pass that up."
