Who Has Whose Hair: Justin Bieber Vs. Miley Cyrus [POLL]

Has anyone noticed the similarity between Justin Bieber and Miley Cyrus' hair? They both almost look the same to me, but I wonder who had the look first?

A lot of trendsetters are in Hollywood and the music business. Both of these very recognizable artists could have easily made their hairstyle their own, but what do you think?
