Many people are confusing the hook vocals with Liz Rodrigues.
This is from Skylar Grey's twitter page: (http://twitter.com/skylargrey)
"ACTUALLY, it's me singing the hook on Dr. Dre's "I Need A Doctor." I also wrote it.

Is it safe to assume the track will be on Detox? If it was an Em featuring Dre, wouldn't she have said "on Eminem's I Need A Doctor"?
