As if we couldn't get enough of Katy Perry, she'll be hitting the big screen this summer in a 3D movie.

She's teaming with Paramount for a documentary-style film all about her life.

“Finally, my movie coming out with Paramount this summer! It’s called 'Katy Perry: Part of Me Presented In 3D! #KP3D,'" she tweeted yesterday.

Something tells us that thematically it will be along the lines of "Justin Bieber: Never Say Never."

In unrelated news, are Katy Perry and Kanye West an item?

Sources say they were spotted together after 'Ye's fashion show in Paris, and rode with him to the afterparty.

“Katy and Kanye were near each other all night, not all over each other, just close like they were trying to hide it,” said a source. “And after about an hour, they both inconspicuously left together.”
