The 65-year-old guitarist has been dating theatre producer Sally Humphreys for six months, and proposed to her last week (ends28Oct12).
A source tells Britain's The Sun, "Ronnie and Sally have been friends a long time. He always had an eye for her but she was in a relationship. They've been inseparable for months and he decided to tie the knot again. (Bandmate) Keith Richards has been laughing about it. He's sick of buying him wedding presents."
Wood split from Jo, his wife of 23 years, after his affair with a Russian waitress was exposed in 2008. He was previously married to Krissy Findlay from 1971 to 1978.
