To say that Katy Perry is a hugely successful singer is, obviously, an understatement. But with the upcoming release of her film, ‘Katy Perry: Part of Me’, which chronicles her chart-topping rise to fame, does the songstress now have her sights set on movie stardom as well? “That’s a lot responsibility,” Perry told E! News. “I have friends that are actors, and I see how incredibly hard they work,” she added. “And I work incredibly hard, but I’m kind of the captain of my own ship and as much as I love to collaborate with my team, when you do a film, you have an even bigger community of collaborators. And I’m just very careful of everything I do, because I know who I am, and I don’t want anybody to think that they can make me into something else.” Perry went on to stress that just because she’s good at her day job, it doesn’t mean she can automatically make the leap to movies. “I think that it can sometimes come back to shoot you in the foot,” she said. “So, we’ll see.” Meanwhile, Perry helped kick off Fleet Week with a special concert for troops. Before Perry went on stage, she told MTV News that she was thrilled to put on a show in the troops’ honour. “I think if anyone deserves a party, I think it’s probably the people in service. They are the ones that are actually deployed and protecting us from all the bad guys, and they deserve to celebrate, and they deserve to be celebrated,” she said. “It’s really exciting to see a lot of seamen in white. It’s really cool to be a part of this and be entertaining for them.”
