Rocker, 65, marries 34-year-old
The Rolling Stones star, 65, has known the 34-year-old theatre producer for nine years.
Earlier this year, she told the Press Association he proposed after asking her father's permission at the premiere of the Rolling Stones documentary, Crossfire Hurricane.
She said: "There's no problem with the age difference. I can understand why people would have a problem with it but it doesn't seem to cause any problems. We get on very well."
Humphreys added: "He's very funny and very talented. There's the Ronnie that everyone thinks that they know and the very talented artist and musician."
Wood, who has battled addiction to drink and drugs, split up with second wife Jo in 2008, after he left his wife of more than 20 years for 21-year-old former cocktail waitress Ekaterina Ivanova.
His divorce from Jo was finalised last year.
His first marriage, from 1971 to 1978, was to Krissy Findlay, the mother of Jesse, one of his four children.
Second wife Jo recently auctioned off items from their marriage, sparking a dispute with the guitarist who said his Rolling Stones tour outfits were not hers to sell.
The band recently played a string of concerts marking 50 years since their first gig.
