Report: Woman accuses 'Voice' star Cee Lo of drugging her drink and having sex with her

The woman who filed a police report accusing Cee Lo of sexual battery secretly recorded a conversation with the singer in which he admitted to giving her a drug and then having sex with her, TMZ reports, something the singer denies.

The woman has told police Cee Lo took her to a downtown L.A. restaurant in July. They had a drink and she says she remembers nothing after that. The woman claims the next thing she knew she was lying naked in a bed and Cee Lo was in the room.

We're told the woman, who does not live in California, almost immediately went to her local law enforcement agency and reported the incident. The matter was eventually referred to the LAPD.

Sources tell TMZ that LAPD detectives had the woman make a "pretext call," a call in which someone baits the other party into acknowledging a crime or other misdeed, and it was recorded.

Sources involved in the case represent to TMZ that Cee Lo is on tape, repeatedly apologizing and referencing MDMA (Ecstasy), though he does not specifically say he put it in her drink. Sources tell TMZ that Cee Lo told her he thought the drug would help them have an exciting time together.  For the record, MDMA generally does not render people unconscious.

Sources connected with Cee Lo scoff at the claim, saying if the tape contained such admissions Cee Lo would already be under arrest. They also tell TMZ that the accuser went to a civil lawyer before going to police and demanded money from the singer to make the whole thing go away.

Other sources tell TMZ a different story: that her lawyer called Cee Lo's manager to find out if the singer had any communicable diseases and never made any money demands.

TMZ's Cee Lo sources say the manager shut the lawyer down and that's when she went to cops. Other sources say she called the cops before her lawyer called Cee Lo's manager.

As TMZ first reported, detectives went to the restaurant last week to determine if employees saw anything unusual between Cee Lo and the woman. LAPD detectives will refer the matter to the L.A. County District Attorney's Office when the investigation is completed.
