There is some history behind Dr. Dre’s Detox single, “I Need A Doctor.” The vocals, sung by Skylar Grey, were originally supposed to be Lady Gaga’s. In an interview with HipHopDX last July, she said while penning the hook to “I Need A Doctor,” the label wanted to put Gaga’s vocals on the song that also featured Eminem. 

“Somebody in the room suggested we get Lady Gaga to sing the hook on 'I Need A Doctor' and [Eminem] stood up for me and said no, because he wanted to keep my voice on the song," she said. Thanks to Em’s support, Skylar got a major look, but we can’t help but wonder what Gaga's version would have sounded like.
