2 Chainz, M.D dons scrubs and sits in on a booty lift surgery. "If this procedure costs 10k, and I got a 40 on me...how many booties can I help out?" 2 Chainz can cross another accomplishment off his bucket list. Decked out in a set of scrubs, Dr. Chainz spent yesterday afternoon sitting in on a "Brazilian Butt lift." TMZ reports that surgical procedure was carried out by Dr. Michael Salzhauer, aka Dr. Miami, and the rapper's presence was fully consented by the patient. Judging from the pair of videos, Chainz comes off like a kid in a candy store, his voice thick with barely restrained glee.
