The 90-minute, needlessly 3D documentary Katy Perry: Part of Me is a fantastic document of how guarded our superstars come in 2012. There's more revealed about Madonna in a single snort or eye roll in 1991's Truth or Dare than there is Katy Perry in the entirety of Part of Me. We learn that being a famous singer is Perry's childhood dream come true, that her goal is to make people smile, that she's not yet ready for kids. The biggest revelation is that she looks fantastic out of makeup, and if the words in her Proactive commercial are true, even that shouldn't come as a surprise. No warts at all.
