It's been an emotional roller coaster. I’ve had my ups and downs, but this experience is unreal—I mean, Nick Jonas sang my song!
I honestly couldn't tell you. I think it's a typical pop song that a bunch of people could sing. I don't know what was so special about it that made it go viral.
They were simple, but catchy and clean. I thought it could really go big.
I like the backseat so you can talk to all your friends without having to turn around.
What's your ideal Friday night?
Right now it would be to get some sleep, but typically I just want to hang out with my best friend, watch movies, and be a dork.
And who's your Friday-night dream date?
Justin Bieber.
Did you watch him on YouTube before he went mainstream?
I had seen some of his videos before he was “The King.” I wasn't a huge Belieber, but I thought he was talented.
What are some of your favorite viral videos?
I’m a big fan of Greyson Chance. I watched his first video like 20 times. He's adorable! It’s so cool that he was at a school talent show, and it just went viral like that.
What artists inspire you?
I mean there some people who have had a little jump start in the business, like Miley Cyrus, but watching Justin Bieber become big when he was so young was insane. I never thought I could be anything like him, and now people are comparing me to him!
Would you say you’re more like Selena, Miley, or Taylor Swift?
People tell me I sound like Taylor Swift. Once you hear my sound without any adjustments—just my raw voice—it’s unique.
Do you watch American Idol?
I watch every episode. I’ve always considered auditioning when I turn fifteen.
How have your friends reacted to your success?
They are so happy for me, but school has been really different. I get a lot more attention, random people are coming up and saying, “hi,” like they've known me for years. It’s weird.
It was pretty brave of you to join Twitter after some of the harsh comments you talked about getting on YouTube, what made you decide to do it?
I was really pissed off that there were all these impersonators. They were making me look bad, so I wanted to show everyone that those people weren't me. At first I had to quit my social networking sites because of what was happening. Now Twitter is my little place.
I know you’re donating some of your earnings to charity, but what's the first thing you are going to buy for yourself?
I'll probably buy a bunch of stuff from Forever 21. I really don't have a lot of clothes.
Describe your personal style.
I change my style a lot. Sometimes I feel like going totally boho, but other times, like now, I’m wearing heels and a trench coat, with a chic dress. I love Betsey Johnson.
Did you want to be famous?
I thought it must have its perks and cons. But I'm only thirteen, and I think every young girl wants to be famous at some point.
If you could do it all over again, would you?
Definitely.

Most played song on your iPod?
Just the Way You Are by Bruno Mars.
Favorite sweet?
I'm a chocoholic, so M&Ms or even a Hershey's bar.
If you could have any superpower, what would it be?
To be invisible. I would mess with some people.
What are you reading right now?
I just finished The Hunger Games. I loved it. It’s my favorite series of all time—above Twilight and L.A. Candy, by Lauren Conrad.
