A month after splitting from Katia Ivanova, the 62-year-old Rolling Stones guitarist took 26-year-old Hannah Kamelmacher on two dates last week - to a Chinese restaurant in Surrey and the Masters Snooker tournament in London - and according to friends of the public relations worker, she has already stayed at his Surrey mansion.
A friend of Hannah's said: "She said Ronnie was really keen on her. They spent time together on Friday (08.01.10) at his house and she stayed the night. I know the first night they met he wanted her to go back to his place but she said no.
"She gave him her number, but wasn't sure if he'd actually call."
Ronnie's original rollercoaster relationship with 21-year-old former waitress Katia resulted in the end of his 23-year marriage to Jo Wood, who reportedly spotted him and his latest lover at the Chinese restaurant when she took one of her grandchildren to the cinema next door.
A source said: "She popped her head in and said hello - but didn't sit down and chat. Ronnie looked totally shocked."
Friends are now worried about Ronnie's conduct, after his 18-month relationship with Katia ended with a blazing public argument during which he threatened her. Katia later blamed Ronnie's drinking for the split.
A source told The Sun newspaper: "It's very worrying after what happened with Katia and how destructive his life became when he was with her."
Hannah, whose family hail from Russia, refused to comment on the fledgling relationship.
