Ben Stiller caused a stir with his recent post on Instagram of him cracking out his best Zoolander pout opposite none other than Justin Bieber, who looks to be doing his best to immitate it. Stiller captioned it ‘#Zoolander @justinbieber’…keeping things enigmatic then. But we’re fairly sure this means Bieber is going to be joining the ranks of Zoolander 2 cameos.
