Oprah Winfrey
Back in the ’90s, Oprah Winfrey tearfully admitted on her talk show that she’d been a cocaine user in her 20s. A recent tell-all book from one of her former boyfriend’s claims that Oprah was still using during the ’80s in the early years of her show. The truth of the matter is still unsure, but it is clear that Oprah has overcome whatever addiction she had to cocaine.
