A girl finding any excuse to touch you is one of the sure signs a girl likes you.
If this happens several times in a row, it usually means he's not that interested in the conversation, or he has a bad phone. :/
Early in his career he literally sounded like a 6 year old girl, and I guess people still really hate him for that. It's not even his fault, though. And I'm guessing Justin Bieber's music is mainly targeted towards tween/teenage girls, so if guys listen to "little girl music", then they could be labeled as gay.
