Rihanna will collaborate with Coldplay on "Princess of China" for "Mylo Xyloto" Album
Maybe 2nd Single

But... Not is the first Time:

Why there is Rehab on that list?

her voice is perfect hook material.

Well, I see that her lack of a strong image and artistic integrity (meaning that the other artist can bend her/her persona to his/her wishes) made her the #1 to go to popstar for collaborators

Rihanna is amazing on features! LTWYL was SO massive

Is this even a question?

Yep, Maybe will make a Remix for Katy Perry ?

I don't think so. She's good but she's definitely not a queen.

And your fave is?

WHA...
looks @ post count

Not a feature queen to me, she doesn't really hop on a lot of other records. but she does deliver on features

Yes, but her biggest hits have no features like some other girls

Nicki Minaj Too, is other featuring's Girl
