The death of actress and children's TV presenter Natasha Collins is thought to be non-suspicious at this stage, an inquest has heard.
Ms Collins, the fiancee of fellow TV presenter Mark Speight, was found dead in the bath at the couple's penthouse home in St John's Wood, north-west London, last Thursday.
The short session of the inquest in London was adjourned until Wednesday February 20. Mr Speight did not attend the hearing.
He was arrested on suspicion of murder and supplying Class A drugs after Ms Collins's body was discovered. He has since been bailed by police until early February.
Mr Speight has insisted he had nothing to do with his fiancee's death.
Initial postmortem results were inconclusive, and further tests are deemed necessary to determine the cause of death.
