Keri Hilson

We've been seeing her all over the place but what we want to know is this- is she a real singer or some session stand in?

We first noticed her on Timberland's "Way you are" (or whatever it's called).
Next we see her with him again on "Scream", outvamping Nicole Pussycat (her sexiest moment to date).

After that she appears as the girl in Usher's "Club" vid (though doesn't sing on the track).

Other cameos include Nelly Furtado's Promiscuous and Fergie's Party People (right at the end - blink and you miss her).

Now she's singing on the new Chris Brown track.

Question is, will she ever release anything under her own name? Keep watching.
