This is the cutest thing EVER!
Did you know Jesse McCartney is a super talented voiceover actor? He was Theodore in the Alvin and the Chimpunks movies and he's a permanent character in the Kingdom Hearts video games.
I had no idea until a fan tweeted at me to ask him about the release of Kingdom Hearts 3!
So cool!
Watch Jesse break down how they create Theodore's voice below:
