Dr. Dre's alleged mistress Crystal Sierra aka Crystal Rogers was spotted with the music mogul in the recording studio earlier this year.
Back in September, the actress/songwriter/music producer posted a photo on her Instagram. In the snap, Crystal is seen standing in the studio with Dre, along with a team of other people.
She captioned the photo, "Hard work=Earning a Seat to work with the Best. A lot of talent in this room. #hiphop #hip #legends #musician #protools #beats #rapper #singers #singersongwriter."
A bunch of Crystal's friend left comments saying they were proud of her hard work.
