Ron Wood's wife of 23 years, Jo Wood, has left him and is planning to move to the U.S. while Wood completes his most recent stint in rehab.

Earlier this summer, Wood fell off the wagon and during his latest drinking binge, left his family and moved into his Irish mansion with 18-year-old Russian waitress Ekaterina (Eka) Ivanova after meeting her at the premiere of the Rolling Stones' latest concert film, Shine A Light. Although Wood is currently sober, he allegedly is still romantically linked with Ivanova.

A source close to the Woods told thesun.co.uk, "Ronnie is making good progress in his battle with booze. His family hoped his fling with Eka happened because he fell off the wagon. Sadly for them, he has genuinely fallen head over heels for her. He's like a lovesick puppy and can't shake off his teenage-like infatuation. Jo's moving to the U.S. to piece her life back together. Being away from memories of Ron will do her good."

While in the U.S. Jo Wood will be promoting the work of her brother, painter Paul Karslake, including his remake of the Da Vinci's The Last Supper featuring such rock icons as Wood, Mick Jagger, and Jimi Hendrix, among others.

Ron Wood, who last entered rehab during the band's mammoth 2005 to 2007 A Bigger Bang tour, reportedly was drinking two bottles of vodka a day prior to checking himself in to a Surrey, UK facility.
