United Kingdom, Sept. 25 -- Jo Wood warned her children not to steal Keith Richards' cocaine.

Ronnie Wood's ex-wife has revealed the Rolling Stones star's bandmate was a regular visitor at the family home while they were married and she had to tell her young kids not to touch the guitarist's drugs after he racked up "massive lines" of white powder on their coffee table during an overnight stay.

Jo, 71, told The Times newspaper: "I remember Keith was staying with us and he was stretched out on the sofa with a bottle of Jack Daniel's and all these massive lines of coke on the coffee table.

"I took the kids to one side and said: 'That is Uncle Keith's. Don't you dare touch it'."
