Former Westlife star Brian McFadden considers his new marriage to be effectively his first - and said he had no idea what he was doing when he tied the knot with his ex, Kerry Katona.
The Australia's Got Talent judge married Irish model and DJ Vogue Williams at the beginning of September in Florence, Italy.
In an interview with Hello! magazine, McFadden said he has a "completely different life" to when he and Katona staged their wedding a decade ago.
He said he considers this to be his "first time getting married".
McFadden, 32, said: "This is me getting married for the rest of my life - and a completely different life. I was 18 or 19 when I got married the first time. I was in Westlife. I had no idea what I was doing. It wasn't till I was 30 that I turned into an adult."
He and Williams married less than 18 months after they met in a Dublin nightclub. They chose a medieval Tuscan castle in Italy because they wanted to keep their wedding relatively small and saw it as a "halfway" location for friends and family flying in from both Ireland and Australia, where the couple now live.
McFadden said: "You can't get married in Ireland and only have 80 people."
Dannii Minogue, a guest at the wedding and also McFadden's Australia's Got Talent colleague, said: "They make a beautiful couple and I wasn't surprised at all when they got engaged."
McFadden, who was engaged to Delta Goodrem for four years, said Williams, 26, had the effect of "taming" him. He said he had never done any domestic chores before.
"Vogue has made me so happy. She puts a smile on my face every day. She has made me a better person," he said.
The couple said they could not bear to be parted the night before their wedding.
Williams said: "I was asking everyone: Is it that bad if I spend the night with him? So I did and he got up in the morning and left before the bridesmaids came. It was perfect."
McFadden's two daughters, Molly, 11, and Lilly, nine, were junior bridesmaids.
