Ronnie Wood Kat-fight

THE wife of rehab rocker Ronnie Wood is squaring up for a fight with his teenage lover over her old man.

Jo Wood has vowed to SAVE her marriage to the 61-year- old star even though love rival Ekaterina Ivanova had a secret meeting with Ronnie at his Surrey rehab clinic last weekend.

Jo, 53, told pals this week: "I will fight to save my marriage. We will try and work it out."

But 19-year-old Katia is equally certain that she will win over Ronnie, insisting she was "not going to give Ronnie up".

Jo's pals have been urging the mum-of-four to end her 23-year marriage but she is now preparing for a bitter fight with the teenage waitress.

A close friend told us: "Jo is still certain that this Russian girl means nothing to Ronnie.

"She didn't even seem bothered that Ekaterina went to see him." But the pal said it was telling that the Rolling Stone still wanted to see Katia-who turns 20 next week-as he sobered up at the Life Works Community centre in Old Woking. The pal said: "That speaks volumes."

Katia, who is staying with pals in a villa in Corfu, said: "When I saw Ronnie again my feelings were as strong as ever.

"There is a very strong connection between us. It's electric."
