Part of Me singer, Katy Perry, has revealed to MTV how she had to go on a certain diet and also got herself a personal trainer, to help to get her into tip top shape for the music video for the Part of Me single. Katy admitted that she learnt how to do a lot of things, although not everything was perfect.

Perry explained, "I got on a meal plan. I'm still on that meal plan, although I cheat a little bit - I have to live! I got a fantastic person to work me out and get me into really good shape. On the actual base, I did a lot of things. I flipped girls, I learned how to fireman-carry. I know how to carry my weight a little bit more."
Katy Perry then went on to admit that, while she was beginning to master many of the things that she needed to do, she was still having great difficulty with one aspect of the training regime, something that many people will be able to relate tp.

She added, "One thing I can't do, and I hope that there are other people out there that feel the same way, is climb a rope. Oh my gosh, it's so hard to climb rope! It's all about grip and arms. I tried five or six times on set, but I had to cheat that shot. My hands were shaking."
Katy Perry’s Part of Me hit number one in the US and is set to hit number one in the UK this weekend.
