There may be a recording that Cee Lo Green wishes his voice was not on. The woman accusing Green of sexual battery secretly taped a conversation with the “Forget You” singer in which he allegedly admits slipping her a drug – possibly Ecstasy – and having sex with her, sources told TMZ.com. The accuser claims the 38-year-old “The Voice” judge, whose real name is Thomas DeCarlo Callaway, brought her to a downtown L.A. restaurant in July, where they had a drink.
