Everything on this cake is edible with the exception of the wires holding up the stars. If you know anything about Hannah Montana, you might recognize the purple guitar and the Happy Birthday Banner on top that's modeled after the Hannah Montana logo. I did a similar cake to this one a while back and Sophie loved it so much that she wanted something similar. We added the microphone in the middle tier because Olivia loves to sing. Although she was shy, I think Olivia was excited about it all :)

In order to make the shooting stars, I cut out stars from fondant at least two or three nights before the cake is due. I immediately slide a thin wire (I use flower wire) into the stars and then simply let them dry until I put them into the cake. It's very simple but gives it an extra something.
