I asked one date what he wanted. He looked around my house and said, ’Half of all this’

mushrooms. I am obsessed with organic food,” Jo says. “When I grew my first crop of organic potatoes, I didn’t want to leave them. We were going on tour to Paris so I packed them in a suitcase and took them with me.

“I got the cook backstage to cook them all up for me and Keith came up to me and said, ‘The trouble with you, darling, is you’re addicted to organic food’. I looked at him and thought, ‘Are you mad?!’ Patti [Hansen], Keith’s wife, is now obsessed. I think that’s why he’s still alive!” Jo has many stories from her time with the Stones and shares an untold one about artist Ronnie being drunk in the delivery suite as she was about to give birth. She laughs: “Ronnie was like a maniac. He was drinking and he’d been up all night. Jack Daniels. He was drawing me and taking Polaroids between my legs. I’ve still got these Polaroids of the baby’s head coming out. I’ve got some lovely drawings he did of me pushing out the baby.”

Jo has 10 grandchildren who call her “gangster granny” since they asked her, “Gran, have you done any drugs?” and she replied, “Of course!”

She admits she could only balance being a rock star’s wife and mum-ofthree in LA thanks to a nanny called Jay. She says: “We were partying a lot then. We’d stay up all night and have a house full of musicians, roadies sleeping on the floor. It was insane.”

Saturday nights are a bit different for Jo now, though. She loves watching Strictly after appearing on the show with Brendan Cole in 2009, and credits it with giving her a muchneeded ego boost.

“I’d just split up with Ronnie,” she explains. “I’d lived so much on his coattails… I was on my way back to being Jo again.

“Afterwards, I thought if I can do that, I can do anything. I was so proud of myself.”

Jo, who rates this year’s contestants Angela Rippon and Layton Williams, added: “It was very good for me… it’s good for anybody to do it.”
