Jo Wood has tried everything to get her husband to come back. Her kids have intervened. So have friends. But maybe the thought of paying $90 million may finally make Ron Wood sober.

As we reported in July, The Rolling Stones star, 61, was having an affair with Russian cocktail waitress Ekaterina Ivanova, 20 who encouraged his drinking and offered freeflowing vodka among other vices. Finally, after countless pleas from his family, Wood agreed to go to rehab.

But now that he's out, he's out and about with Ivanova again and was just seen taking her out to a London restaurant.

Natually the London papers caught them. And now Wood's wife Jo, 53, is fuming mad. After 23 years of marriage, she has consulted with divorce lawyers.

Jo Wood told “The Daily Mail”: "We've been through too much together not to stay as friends whatever happens next. … Despite everything I still really care for Ronnie."

Sounding the way we hope all women going through divorce will sound, she said: "Everything is fine, and everything is going to be fine.”

And she admitted that after spending “so many years concentrating on Ronnie … suddenly I can now concentrate on me.” And if that weren’t enough, she said, the stress has made her drop a little weight.

As has benn reported, Wood's wife has played an integral part in his career, working as his executive assistant, holding a controlling stake in the couple's finances, and acting as his personal management assistant on a number of profitable deals. Jo also serves as a joint director of Rockyarch, a literary and artistic limited company Ron Wood incorporated in 1986, and is company secretary for his fine art publisher and gallery Scream Art.

What this means is that she has extensive claims to his considerable estate — and is entitled to it.

Here is a wife who has been an integral part of his personal and professional life and would only want her fair share. But it is clear that she loves her husband and is more interested in keeping her family intact.

If they do get divorced, Ron Wood is likely to owe Jo more than Paul McCartney's $48 payout and Phil Collins's $50 million. When marriages are no longer harmonious, these musician husbands will have to pay to the tune of millions.
