If there's anything we learned from PopCrush's 2013 Celebrity Yearbook Superlatives polls, it's that you should never, ever mess with Directioners or Beliebers. They will always win.

One Direction and Justin Bieber totally dominated our reader-voted superlative polls, with the Biebs snagging Best Hair among other accolades, and the One Direction guys sweeping categories like Best Eyes and Best Dressed.

Little Mix also snagged a couple titles, with Perrie Edwards and Zayn Malik earning the Cutest Couple laurel, and the girl group itself scoring the Most Likely to Succeed superlative.
