The Rolling Stone star entered rehab on 16July for the second time in a month amid rumours he had left his longterm wife, Jo, and had a booze-fuelled fling with a 20-year-old waitress Ivanova.
It has been reported Ivanova had worked as a prostitute and only dated 61-year-old Wood because of his wealth.
But she has strongly refuted the claims.
"They're calling me a Russian slut but if that's the case I'd be with a rich businessman, not Ronnie," Contactmusic quoted her, as saying.
"I'm not a prostitute and I've never worked in an escort bar.
"We're in love, we're completely in love," she added.
