2015 was an eventful year. So many things happened in pop culture from music to movies and social media trends. Here's just a few:

1. "50 Shades of Grey" came out the day before Valentine's Day.

And a bunch of girls went to go see it.

2. Zayn Malik left One Direction.

And broke the hearts of many Directioners.

3. Bruce Jenner becomes Caitlyn Jenner.

4. Travis $cott got arrested for starting a riot at Lollapalooza.

5. Adele made a comeback with "Hello."

And won the hearts of everyone.

6. Justin Bieber released "What Do You Mean?", "Sorry" and his new album. Everyone became a Belieber again.

7. He also went blonde.

Still didn't keep anyone from becoming a Belieber again, though.

8. Lollapalooza decided to add an extra day onto their 2016 Lineup.

Probably the best decision ever, but now we have to wait for the lineup...

9. Frank Ocean still didn't drop his new album.

Not that "Channel Orange" isn't great and all, but c'mon Frank, we've been waiting.

10. Drake's "Hotline Bling" video came out.

The dance is much harder to imitate than it looks.

11. Donald Trump decided to run for president.

Still not sure if this was such a good idea, Donald. #you'refired.

12. Kendall Jenner got to walk in the Victoria's Secret Fashion Show.

AKA, every girls dream.

13. We can't about #thedress social media phenomenon.

You know, the one that stressed everyone out?

14. Essena O'Neill revealed the secrets of what it's like to be an Instagram model.

She reinforced that you only see what people want you to see on social media.

15. "The Hunger Games" trilogy (except movies) finally ended.

Looks like we'll have to find a new series to watch now..
