I'm trying to teach my granddaughter a life lesson using Zac Efron and Marlon Brando. Can you help?

I've noticed that my granddaughter is bordeline breaking the first commandment (Exodus 2: 2-6) with her constant worship of Zac Efron. I am going to show her some pictures and movie clips of Marlon Brando when he was young, and then show her some pictures of Marlon Brando when he was fat and ugly. My whole point is that physical beauty is only temporary, but I don't know where to take it from there. Thanks in advance.
