Happy 18th Birthday Justin Bieber! 3 Songs About Coming of Age...

It's time to make you feel old (or maybe really young): Justin Bieber turns 18 today. YUP, he grew up before our eyes in the spotlight and now he's finally saying goodbye to his youth and transitioning into adulthood. It's been a fun ride so far and something tells us he's not done taking over the pop world. Here are 3 coming-of-age songs dedicated to Justin on his birthday....

Jay-Z - Young Forever

So we livin' life like a video where the sun is always out / And you never get old and the champagne's always cold / And the music's always good / And the pretty girls just happen to stop by in the hood

This is a song about appreciating your youth and living in the moment forever, and ever, amen. That's something we can get behind Jay-Z! It must be easy to live for today when you have no worries or cares on the financial front, right Justin? Happy birthday!

Alice Cooper - I'm Eighteen

Well, I got a baby's brain and an old man's heart / Took eighteen years to get this far / Don't always know what I'm talkin' about / Feels like I'm livin' in the middle of doubt

This is kind of like the rock'n'roll dude's version of "I'm Not A Girl, Not Yet A Woman". It solidifies the fact that 18 isn't all that old. It may seems like a great age when you're younger but once you turn 18 it doesn't feel like much, and you're still as confused about who you want to be as ever. Maybe Justin will be comforted with the fact that he already has a steady and crazy-successful career.

The Pussycat Dolls - When I Grow Up

When I grow up, I wanna be famous / I wanna be a star, I wanna be in movies / When I grow up, I wanna see the world / Drive nice cars, I wanna have groupies

So, Justin is still in the process of growing up (I guess we all kind of are) but he has everything the Pussycat Dolls sing about in this song: Famous, check. Movies, check. See the world, check. Nice cars, check. Groupies, double check. Not too shabby JB!
