Wood previously claimed he was planning to marry Humphreys - who he popped the question to in October after just six months of dating - early next year, in a bid to keep their nuptials a secret.
Humphreys also revealed they had not ruled out having children together, saying: "Maybe. There are no plans but there are no non-plans."
Humphreys is Woods third wife after the late Krissy Findlay, whom he was wed to from 1971 to 1978, and Jo Wood, who he was married to from 1985 until 2008, when he left her for a 21-year-old cocktail waitress.
The couple have known each other for a number of years, but the time had never been right for them to get together before, according to Humphreys.
She previously explained: "Ronnie was married and then Ronnie wasn't married. I have had boyfriends, then I didn't have a boyfriend. It had to wait until everyone was clear. But I definitely feel like I have ended up in the right place."
She also said she's not worried by the 31-year age gap between them.
"There is an age gap. I would prefer it if there wasn't but there is but maybe I'm a bit older and he's a bit younger at heart.
"Actually, I think that's good in a way. That's what people should be doing, looking after each other.
"On the other hand, I could be struck by lightning or knocked down by a bus. I can't not allow good times now because in 20 years' time it will be different."
