Katy Perry has released the official photo of her documentary movie in 3D, 'Part of Me' on Twitter.

The poster shows the simple teenage dream that Katy Perry once was and the famous pop star that she is now in the mirror's reflection. The trailer also shows that it will tackle her divorce with ex-husband Russell Brand.

It also shows headlines of her tours selling out, her top singles, and all that pressure of a rising celebrity, with the eyes of the world entirely on her.

Despite all the sad parts of Katy Perry's story, the documentary movie that can be compared to Bieber's 'Never Say Never' will serve more as an inspiration to other aspiring artists out there. It will show the humble beginnings of the 'Fireworks' singer and how she also struggled to get where she is now.

Perry's message to its audience is that anyone who wants to fulfil their dream must not stop pushing through that journey. She said in a statement that after seeing the film, people will get to know the real her behind those colourful costumes, the eccentricities, her highs and lows and the rest of her life's ride.

Check out below the official Australian trailer of 'Katy Perry: Part of Me 3D':
