Rolling Stones guitarist Ronnie Wood is engaged to be married to a 34-year-old theatre producer named Sally Humphreys, his spokesperson said on Tuesday.

The twice-married, 65-year-old musician and artist separated from his second wife Jo Wood in 2008 and had a public disagreement with her over the auction of some memorabilia in Los Angeles which went ahead earlier this month.

News of the impending wedding comes just after the Stones played a warm-up gig in Paris for 350 people and announced four dates in London and New York to celebrate their 50th anniversary.

It also comes ahead of the release next February of Jo Wood's memoirs, which promise to reveal her tales of life as the wife of a Rolling Stone.

Wood has recently been focusing on his visual art career and in April opened a New York City art show entitled, "Faces, Time and Places", featuring portraits of Mick Jagger, Keith Richards, Charlie Watts and other celebrities.

But he is still best known for his music and in April was inducted for a second time into the Rock and Roll Hall of Fame, with other members of his former group The Faces, including Rod Stewart and Kenney Jones.

The Rolling Stones, which Wood joined in 1975 after Mick Taylor left the band, were inducted into the Hall of Fame in 1989.
