Behind The Scenes Of Katy Perry's 'The One That Got Away'

From Teenage Dreams to grandmas, Katy Perry keeps topping the charts.

The singer recently took her tale of lost love and packed it into a video, and now she's released all the gory details in her MTV special "The Making Of 'The One That Got Away.'"

"I had written a treatment for the video and sent it out to a few people, and then Floria [Sigismondi], who I had worked with on 'ET' before, sent me a treatment completely revised from the idea," Perry said. "It kind of threw it on its head. It has a little bit of what I started with, and the general idea is the same, but she really took it to the next level."

Apparently someone's idea was good, if not a little terrifying, as Katy Perry transforms into a wrinkly old lady over the course of the video. Which is fascinating; as long as Russell Brand likes the looks of the woman he plans to grow old with.
