1. Aaron Carter
Then: Obviously started the choker trend. Iconic.
Now: He looks like an off-brand Justin Bieber.
2. Chad Michael Murray
Then: Cute. Trendy with his spiky hair. Wore this t-shirt/collared shirt combo tho. Points must be taken away.
Now: Aged like a fine wine. Learned how to raise eyebrow for photos. Nice.
3. Zac Efron
Then: Was definitely wearing a hat before this photo. It was probably a snapback.

4. Lil Bow Wow
Then: You just knew he was going to grow up to be fine.
Now: You were 100% correct.
5. Channing Tatum
Then: Step Up was a great film. Had that "bad boy your mum told you not to go near" vibe.

6. Pete Wentz
Then: Um, there was a lot going on with '00s Pete Wentz. The guyliner, the hair, just wow.

7. Ben McKenzie
Then: Mmmmm not my flavour. But I'm going to be attacked in the comments if he's not in here.

8. Corbin Bleu
Then: That baby blue button-up is really something. Props to him.
Now: Less fro, more chest hair. Same shirt, different colour.
9. Adam Brody
Then: Nerdy. Cute. Curly hair. Dimples. Just wow.

10. Wilmer Valderrama

Now: He got more stubble and lost the beanie. I approve.
11. Jesse McCartney
Then: Rewind it back 10 years ago and I would've given him my "Beautiful Soul". ;)
Now: He's got dark hair now. That's nice, a bit of a change is always good.
12. Ashton Kutcher
Then: He was that weird kind of sexy. The goofy kind of sexy. Plus he had a lot of hair.
Now: Tbh I think he looks better older. Or it could be the tuxedo. Who knows?
13. John Cho
Then: Spiky hair was really the style of the '00s it seems.
Now: Pushed that hair back. Good decision.
14. Jared Leto
Then: Look at those big, beautiful blue eyes. Amazing areas.

16. Nick Lachey
Then: This really isn't my vibe but people loved Newlyweds: The First Year so here we are.

Then: Real-life porcupine aesthetic.
Now: Stubble? Check. Less spikes? Check. Perfect. That's all we need.
22. And Justin Timberlake
Then: I don't know what the fuck his '00s look was. Did people find this attractive? Anyone?
Now: Beards make everything better. Plus his new hair is a real improvement but one of his eyes look fake. I need an explanation.
