I don't want her to ever grow up. Because as frustrating as the "why?" gets, she makes me laugh. I love to hear her singing...even if it's just her singing "I don't wanna take a bath" to her teddy bears. I know I'm going to miss those days so much when she's a teenager.
I believe they're singing the Jordin Sparks/Chris Brown hit "No Air"...at least, that was the last thing I saw.
