Rihanna Teases Potential Katy Perry Duet

Rihanna has revealed that she will definitely work with Katy Perry on a musical project in the future, saying it's more a case of when, not if, they get down to it.

The two girls are close friends and regularly spend time together at parties and award ceremonies as well as going on holiday together. However, despite both of them collaborating with numerous stars in their career, they have never got it together and laid down a track together.

Speaking to Access Hollywood about the chances of this changing in the future, RiRi says:

"We have been working on this for years. We still are trying to make a song together, Katy Perry and I."

Adding: "The song will probably come out in a while. I won't say it's happening right now. But it's gonna happen."

Speaking more generally about her friendship with Katy, Rihanna went on to say: "Whenever we're in the same city we try to do something, whether it's seeing each other for five minutes for a hug or whether it's partying all night."

In another interview yesterday, Rihanna claimed that her current relationship with violent ex-Chris Brown is perfectly 'innocent'.
