Does Katy really do everything herself?

After seeing Katy in many movies like: 

• Looper
• Yes Man
• Paranormal Activity
• and a lot more...

While she has played all these movies she also has another music band called "She & Him", so it got me wondering, is Katy Perry really doing all this or is she getting help from her mighty father?

    She & Him - In The Sun

As we all know Yoda from Star Wars is Katy's father and Yoda has mighty powers.
