Add rapper Nas to the long list of MCs set to guest star on Dr. Dre's much anticipatedDetox album. Escobar recently paid a visit to BET's 106 & Park show to hype his "Nasty" single when he confirmed that he laid a few bars for the West Coast king.

During Nas' chat with BET host Rocsi he also touched on fallen star Amy Winehouse.

"She was a genuine person," said Nas. "She was like, real. When you talked to her, she was real. She was struggling with a lot of things in her life, but she was a real artist. She was like a sister to me, like a little sister. We had the same birthday so she just had this big, big spirit for this little body. You know what I mean? I wish she was here today, man. God bless her soul."
