The Rolling Stones guitarist has reportedly asked 34-year-old producer Sally Humphreys, who he started dating earlier this year, to marry him, according to The Sun newspaper.
Ronnie split from Jo Wood four years ago after 24 years of marriage - when he ran off with 18-year-old cocktail waitress Ekaterina Ivanova – but their divorce was only concluded last year.
While the former model - who has children Leah, 33 and 28-year-old Tyrone with Ronnie – says she will "always love" the 65-year-old rocker, she admitted they had some terrible times in their marriage.
She recently said: "I'll always love my ex-husband, but when I look back on stuff, I do think, 'Ooh, what a rotten b*****d he was."
Jo also revealed she broke down in tears when she had to leave their final marital home.
She said: "I loved that house so much. It was like being a princess in a castle, and I was really sad to go. I knew that I couldn't stay there on my own - it cost so much to run - but it was heartbreaking. I cried my eyes out when I left."
