Celebrities appear to live such glamorous lives, but it’s important to remember that they’re just like the rest of us.

They have bad hair days, marital problems, and awkward adolescent phases.

Some celebrities are unlucky enough to have their high school years immortalized in yearbook photos.

A few look just the same as they do today, while others are completely unrecognizable.

Check out how their high school days measured up to yours:

1. Alec Baldwin

Baldwin is looking much more like his younger self after his impressive weight loss.

2. Matthew McConaughey

McConaughey was voted “most handsome” in his graduating class – go figure.

3. Blake Shelton

Hard to believe that mulleted cowboy grew up to be People’s Sexiest Man Alive.

4. Ashton Kutcher

5. Justin Bieber

6. Barack Obama

No surprise here, but the teenage Roberts looked just like her famous niece.

8. Tom Cruise

9. Beyonce

10. Taylor Swift

11. Jennifer Aniston

12. Amy Adams

13. Cameron Diaz

I wonder if Diaz’s nearly-identical sister rocked the same awesome hairdo in high school?

14. Katy Perry

In case you didn’t know, Perry had a serious reason for chopping off her famous locks.

15. Jennifer Garner

16. Angelina Jolie

As Jolie has revealed, her love life was a little bizarre before meeting Brad Pitt.

17. Johnny Depp

Yes, it’s hard to believe but Depp really looked that young once.

You have to wonder if George Clooney’s twins will take after his looks or their mother’s.

Now a movie star, Pratt was just a cashier when he took this picture.
