Guess who?

So there's this girl.
Her rp name is Alison Hime.
Her nickname is Cookie.
She loves to dance.
She also loves singing and acting.
When she has her earphones in, and her MP3 on, you just can't stop her.
Her friends are hilarious, and she'd be nothing without them or her family.
She also does a ton of sports.
When someone asks her where she lives, she just says "In my own little world."
And, last but not least, she's so dumb, she forgot her old password and had to create this new account.
Can you guess who she is?
Me :]
