This is awesome! Justin Bieber teamed up with YouTube's David Dobrik to surprise some unsuspecting students! They were asked about Justin's new single 'Yummy' and then Justin jumped out of nowhere! Their reactions were priceless! One fan actually dissed his new song! lol (Read what he said below)...
When one fan was asked, he responded, love him, but Yummy is just like not it. It's just not that good.
