Hope the popstar. Her own idea, her own creation. I have nothing more to say about it other than this. I'm in trouble.
Ava as Madeline. Ava loves Madeline books and cartoons and we had this cute dress hidden away in the back of the closet. Score! P.S. I think she partly likes Madeline because she says, "pooh, pooh" when she doesn't like something...and Ava isn't allowed to say that, generally speaking.
And Bella as Supergirl...or some version of a girl super hero. Her most powerful weapon is that cute smile!
