Katy Perry "Britney Is Not On The Top Of My List"

Katy Perry has revealed she isn't interested in collaborating with pop princess Britney Spears.

Despite everyone wanting to work with the 'Womanizer' singer since she launched her comeback, the 'Hot N Cold' star told reporters at KIIS FM's Jingle Ball: "She's not on the top of my list. There are other people I'd much rather work with first."

Katy did however reveal one singer she'd consider working with: "I love John Legend's record. So how about I collaborate with him?"

Earlier this week the Pussycat Dolls revealed they plan to collaborate with Britney on a new track and they'll be also be supporting her on tour next year.
