Poster Debut: Katy Perry – Part of Me

Katy Perry – she’s just like us!

The poster for Katy Perry’s upcoming 3-D concert film Part of Me has arrived online, highlighting her evolution from kooky girl-next-door with big dreams to chart-topping, record-devouring, planet-engulfing, mega-star.

Not pictured in this replica of her teen bedroom: evidence of her Christianity, which would inspire her to release a gospel album at the age of 16. Not as sexy as knee-socks, it seems!

We continue to hope this will be surprisingly good like Justin Bieber: Never Say Never.

Katy Perry – Part of Me arrives in Australian cinemas July 5, 2012.
