Oh Lily! Ha ha

Driving in the car, a Whitney Houston song comes on the radio.
Ella: mom, why do you like this song?
Me: I don't.
Then I change the station.
Lily: Turn it back.
I turn the station back. Lily starts wiggling.
Lily: My butt likes this song. See it dancing?

A few minutes later...
Ella: Lily, why do you like this song?
Lily. I don't. My butt likes this song.

I really don't know where she came from.
