Peaches Geldof hid her drug use from her husband, hiding heroin in the loft of their family, her husband Thomas Cohen told an inquest.
Mr Cohen told the hearing his wife had started taking heroin again in February and he had witnessed her flushing drugs down the toilet at their home in Wrotham, Kent.
The musician confirmed that he had gone to stay with his parents in southeast London with the couple's two sons, Astala, two, and one-year-old Phaedra, and that she had seemed fine when he spoke to her on several occasions over the weekend.
The inquest heard that Mr Cohen's father, Keith, had seen Ms Geldof when he dropped her youngest child home to her and she appeared fine. Mr Cohen said he had last spoken to his wife at 5.40pm on Sunday April 6.
