Katy Perry joins the marines after getting out of a relationship gone bad in her new music video for ‘Part of Me.’

“It’s an affirmation of strength, so I wanted to go the strongest route I ever could,” Perry said speaking of the video. “Literally, I was like, ‘I’m gonna join the service. I’m gonna join the Marines.’ We used only Marines. … For three days, I was a wannabe Marine, which was so difficult.”

The few – the proud – the Perry!
