    Baby, baby, baby, nooo! Not-so-little Justin Bieber turns the big 1-8 today, leaving his childhood years behind him. Even though the young pop star has been melting tween hearts for just the last three years, he has definitely made his mark as one of the biggest pop sensations this world has ever seen. To honor Bieber on his special day, we matched him up with some of the biggest Beliebers in the animal kingdom.

    MOVING ON UP  

    Any diehard J-Biebz fan knows that when the singer was starting out, his signature ensemble included two things: sideswept hair and a purple hoodie.

    COIFFURE COPYCATS

    It turns out little boys weren't the only ones who copied the singer's stylish 'do.

    SUIT AND TIE 

    As Bieber matured from sweatshirt to suit, so did his fans.

    PUT A WIG ON IT 

    Not everyone was born with perfect tresses. You do what you gotta do.

    SCARF SWAG 

    What's the perfect way to stay warm, but "cool" (if you know what we mean)? A handsomely wrapped pashmina, obviously. #SWAG

    POP STAR POMPADOUR 

    Elvis did it. Justin did it. Thus, all the alpacas are doing it.

    GEEK CHIC 

    We're pretty sure Justin Bieber has no need for prescription glasses, but these wide-rimmed specs make fans feel like he cares not just about their beauty, but their brains, too. Swoon. This Corgi casanova obviously took notes for his interactions at the dog park.

    FIRST LOVE 

    We were so sad to see Jelena end earlier this year. Bunnies everywhere cuddled closely to pay respects to their fleeting romance.

    NEVER SAY NEVER

    If Justin says camo is back in, camo is definitely back in. When it comes to trends, never say never.

    IN YOUR EYES 

    If there's one thing any budding pop star should know, it's that girls go crazy for a shy smile and a smoldering stare.
