She is a youngest girl in America's Got Talent. I found this out when i was looking for about somewhere out there song. She really wonderful. Maybe its an exaggerating, but my tears are fall. I'm very surprised about it. She sings well. I've never seen like this before.
Kaitlyn sings "Somewhere Out There" that was really awesome. She dressed a cute dress like a little princess. She never looks worry and fear to face more than 1 thousand people in front of her. So big applause for her.
there's a little conversation between the judge and Kaitlyn,
J :"Hey Kaitlyn, When did you start singing?"
K :"Since time I was one."
J :"Wooowwwwww!!!"
