The Rolling Stones guitarist – who had an affair with Russian waitress Ekaterina Ivanova, 20, earlier this year – is a huge fan of the ornaments and could not resist buying them when he was on tour.
A source said: "Ron has loads of Russian dolls. He used to pick them up on the road when he was touring. He has dozens of them stored in his attic at the house in London."
"Years ago he used to have them placed around the house. He liked the simple paintings of the women on them. His kids used to play with them."
Ronnie and Ekaterina enjoyed a 10-day alcohol-fueled trip to his luxury home in County Kildare, Ireland, earlier this year.
After pleas from his family, the 61-year-old musician entered Surrey's Lifeworks rehabilitation clinic to be treated for alcohol, sex and drug addiction.
Meanwhile, Ronnie has been invited to join fellow recovering addict Robert Downey Jr. at an Alcoholics Anonymous meeting.
The "Tropic Thunder" star met Ronnie at London's Claridge's hotel earlier this week when he suggested they should discuss their drinking addictions.
A source told Britain's The Sun newspaper: "Ron was having a soft drink with friends when Robert bowled over for a chat. He introduced himself to Ron and said they should get together for a session."
