Busted.

I set her up in the kitchen with her paints and paper and went to do a few things.
Walked by the kitchen once, she was fine. Walked back by,  heard her talking to herself. Fine.
Came back less than 10 minutes later to this:

It's hard to tell here but she painted all of her hair, too. I just had to laugh.
On the way upstairs to get her right into the bathtub she looked at me very seriously and said;
"Is this just between us?"
Ummm...no hon, I got pictures. You're so busted.
