Why is Ariana Grande getting so popular all of the sudden?

[Aidee]

She's more popular than her costars in Victorious, and she's not even the main character. She's popular around people who like Justin Bieber, One Direction, and Little Mix. Of course, she's my favorite character in Victorious because she's funny(but I don't even watch tv much lol). Yeah. She wasn't even this popular last year and now it's blowing up-- it's all over facebook, twitter, and instagram. I've heard her sing and I thought she was really talented, even more talented in terms of singing than Victoria Justice. I understand "people" only like her because she has red hair, but that would be quite ignorant. I mean there's people in your school who look good in red or blue hair, and they aren't famous.
