Here's How Much Justin Bieber Has Changed Over The Past 9 Years (Photos)

It's pretty obvious Justin Bieber has some of the most dedicated fans out there.

The Belieber fan base has been growing since the moment Justin released his first music video for "One Time" and became an Internet sensation.

Over the past several years, Justin went through A LOT of sh*t. From his breakup with Selena Gomez to his arrest in Miami, there have been some hard times in Bieber's life.

What's been so incredible about his fans is they've stuck with JB no matter what. They've been there to show him support and let him know they weren't giving up on him.

In 2015, JB basically quadrupled his fandom by having the most epic comeback of all time.

His most recent album, Purpose, has been at or near the top of the charts since its release, and people who never used to consider themselves Beliebers are now wearing that label with pride.

OH, BIEBER, YOU'VE COME SO FAR.

Fans went to Twitter today to honor the 21-year-old star because it's been nine years since JB (also known as Kidrauhl) first added videos to his YouTube channel.

Let's start with this throwback right here to really get you prepared for this. Here's one of JB's earliest videos from 2007. HE WAS JUST A BABY.

Here's another of JB singing some Alicia Keys. These are real gems, aren't they? It's crazy to think how much he's grown up.

It's time to travel down memory lane with me and some of his biggest fans. What was life even like before Justin? I'm not quite sure anymore.

HE WAS SUCH AN ADORABLE LITTLE CHILD. I just want to pinch those cheeks, don't you?

"It all started with Justin and a guitar and that's how it will always be."

A lot can change in nine years. He was once a boy, but now he's a man. (MARRY ME?!)

Most of Justin's fans weren't even BORN YET when this photo was taken. Don't worry, bb, I was there... I was alive...waiting.

Can you even believe this is the same person? What a transformation.

This is just straight-up art. There are TEARS in my eyes. God bless you, Justin.

No, really. God bless you and your beauty. Rest your head, sweet angel.

Your fans love you, Justin, no matter what. We all can't wait to see what the next nine years will bring.

XOXO.
