As a lot of us know Justin Bieber came to Philadelphia this past weekend for his "Purpose" World Tour. As I pulled into the parking lot and saw all the girls waiting by the tour buses, I started thinking about how I used to have major Bieber Fever. We went to our seats, and as the lights went down, I found the Bieber Fever creeping up on me again—and as soon Justin stepped on stage, the Bieber Fever took over. All of us still have a little bit of Bieber Fever inside of us and here is why!

1. The hair.

Even though he just recently cut it all off, we're all still a little bit obsessed with it—whether we like it or not.

2. He has amazing dance moves.

If you have ever been to a concert or seen one of his music videos, you know what I mean.

3. The dude sings to all of our hearts.

That's why we love him, right?

4. Did I mention his body?

This is just a bonus.

5. He can play multiple instruments.

Not only does he play the drums, but he plays guitar and piano, too.

6. He has the best music videos.

All his music videos now are insane!

7. That smile.

How can you not love that smile?

8. He loves his fans.

He really does love us.

9. Who can forget "One Less Lonely Girl"?

C'mon, we all wanted to get pulled on stage to be the "One Less Lonely Girl".

10. "Baby" is still a banger.

If you know all the lyrics to this song, you've definitely got Bieber Fever.
