12 Interesting Facts We Learned About Our Favorite Celebrities From 'Carpool Karaoke'

Aside from listening to music, I love watching James Corden's "Carpool Karaoke" on YouTube. It's so funny, and you learn so many interesting things about your favorite celebrities. Did you know that someone snuck into The Jonas Brothers van and hid behind their luggage? Some fans are wild, huh? If it wasn't for this segment, I would have never known that happened to my favorite childhood band. Keep reading to learn more about interesting stuff that happened during "Carpool Karaoke."

1. Bruno Mars wears a lot of hats! Like, a lot!  

He said he wears a lot of hats because he doesn't know what to do with his hair. 

2. He also has an odd request for his change room.

He said he likes to have wet wipes in his change room. Umm, okay. 

3. When talking about stalkers, Louis Tomlinson from One Direction said that he tweeted that he needed some milk for his tea. 

Well, someone showed up at his house with milk. If I were him, I would always be tweeting about how awful it is that I have no french fries to eat. 

4. Fact: Harry loves to play with his hair. 

He fixed it so many times in this video. Can you blame him, though? 

5. Selena loves to drink ginger juice every morning. 

How? It's such a strong flavor. James said it's absolutely disgusting. I believe him. 

6. When asked if she's on the lookout for a boyfriend, she said that she doesn't know. She said she likes to have fun. 

Which celebrity do you see her with? 

7. Who knew that Adele could rap? 

She literally killed Nicki Minaj's song. Please come out with a rap song on your next album. Thank you! 

8. I finally figured out why Sia wears the oversized bangs and bow. 

She said she only wears it when there are cameras around. She's literally the opposite of me! I can't stop posing when I see a camera. 

9. One of Justin Bieber's favorite movie is The Notebook. 

He said it made him cry. Aww! He also said that he is an emotional guy. 

10. Remember when he used to wear a purity ring? 

He said he took it off when he fell in love with an adult and had a real relationship. Love how personal he got.

11. Nick Jonas and Demi Lovato are celebrating 10 years of friendship this year. 

I had no idea that they'd been friends for that long. They also said that they have never hooked up. I believe them! I mean, that would be a little awkward since she did date his brother Joe. 

12. Demi also exposed Nick's Disney love life!

Demi said he dated Miley, Selena, and then back to Miley, then Selena again. Disney love is a confusing love. Nick says that didn't happen, but Demi shut him down. She called him "Lies A Minnelli." That's going to be my new saying from now on.
