R & B song

There is an R&B/Rap song that has a chick in the chorus going "Am .... I ..... S ... X .... Eeeee?" or something along those lines. I can't tell if she's spelling or actually saying something. Any ways, any help would be great.

Thanx

only thang I can think of is

so sexy-twista

I tried that one and it's not it. Thanks though. The chick is singing pretty slow and I can't tell what she is saying. It might be "I'm . . . . So...... Seeehhh xxx ieee"

I don't know. That's just what it sounds like. I think it's a newer song too.

Thanks though.
