Jo Wood has told how she offered some of her children drugs to try when they were growing up.
The ex-wife of Rolling Stones rocker Ronnie offered daughter Leah a puff of a joint when she was 15 - but the teenager was horrified.
When son Tyrone was 16 and Jo found a packet in his room which looked like marijuana but was actually dried herbs, she made sure he tried the real stuff so he'd know what he was buying next time.
"I also gave him a small packet of coke to try one evening. Irresponsible? Perhaps," the former model, who has released her autobiography, Hey Jo: A Rock And Roll Fairytale, said.
"But I would much rather he learned about these things under my roof, where I could keep an eye on him, rather than in some dodgy club taking God knows what."
Jo, who was married to Ronnie for 23 years, said of her children: "They'd see people smoke joints openly. There were times when they were quite small when they saw people doing lines of coke. We were a rock and roll family and I was open and honest."
