Due to the success of Justin Bieber’s Never Say Never and Glee: The 3D Concert Movie, it’s only a matter of time before it’s par for the course for a pop star to release a big-screen flick of their live show — with a little bit of their own backstory to boot. This Summer, Katy Perry will release Part Of Me 3D, which presents her candy-coated California Dreams tour — in 3D! — as well as footage from her life on the road and her journey from aspiring Christian singer to chart-topping pop vixen. Catch the trailer below.
