A new video of Katy Perry from way back in 2001, when she went by the name Katy Hudson, was recently discovered, and shows the pop star long before she was the wacky and wild pop star we know now.
Back then, Katy was a 17-year-old Christian singer playing for small crowds and worrying about the same things every other teenage girl worries about, like her skin and missing her parents. Well, maybe that second part isn't really common with teens.
Take a look at young Katy below, and see four other pop stars then and now in our gallery.
