Because what a better way to promote a performing arts workshop than doing a cover video of Bieber's protégé Carly Rae Jepsen's huuuuge hit single "Call Me Maybe" while having two of the guys of The Wanted doing a cameo on it, uh?
I'm sure it should've been hard for the guys of The Wanted to stop talking shit about Christina Aguilera to take some time for this, right? Awww, how considerate of them!
