Katy Perry Wants To Sing With Rihanna

By Tomika Anderson -- Special to CNN

It looks like Katy Perry has a bit of a musical crush.The "Last Friday Night" singer told MTV she's eying a duet with Rihanna."I've always wanted to [collaborate with her] and she's always wanted to and that's very genuine," Perry said during "MTV First: Katy Perry," which aired on the network on Wednesday. "We're not just shooting the sh--. We're not, like, just kind of beating around the bush. But really we want to."But the pressure just might be too much, Perry said."It's just that I think it's gotten to such a head that if we do something that's not the greatest, it's going to be so anticlimactic," she added. "So we've already thought about it."The military-themed video for Perry's "Part of Me" also premiered on Wednesday.When asked how she got into such great shape for the video, she said, "I got on a meal plan. I'm still on that meal plan, although I cheat a little bit - I have to live!"
