The couple have left Australia to live in London, and Brian said he'd happily stay at home while Vogue heads out to work....
The singer, 33, who has moved back to London with his wife Vogue after a stint in Australia, said it was the experience of his first UK tour in eight years that persuaded them to come back.
He told Hello! Magazine: "We only really decided to move back when we got back."
The couple, who married in Tuscany in September, lived in Sydney for two years - though Vogue admits she missed her family.
"I've never met anybody who has so many close friends," said Brian. "I think she was probably getting a bit edgy in Australia, just being the two of us."
Brian decided to release a new album and tour again after supporting his mentor Ronan Keating this year.
He said: "It was my first time touring in eight years and I didn't know how it was going to be. When I got such a good response after the first few gigs, I thought if ever I was going to come back and put an album out and do a tour, this was obviously the time."
Vogue, 27, said they would like to start a family. Brian has two daughters Molly, 11, and Lilly, 10, from his first marriage to Kerry Katona. She said: "I don't feel I'm in any rush, but it's one of the reasons I wanted to make a base here. I think 30 would be a good age - I still have lots of things I want to achieve."
Brian said: "I'd like to see Vogue concentrate on her career. I'd be happy to be a stay-at-home dad."
Meanwhile, his fellow Westlife member Kian Egan has said he and wife Jodi Albert are too busy with their careers to have another child.
The Voice judge told the Evening Herald, that his wife is busy concentrating on her acting career, so 18-month-old son Koa will not have a sibling for the forseeable future.
"We're definitely not having another one in the near future," he said.
"Jodi is making a move back to work and she has two big offers on the table, so that is our main concern for now."
Kian and his English wife currently divide their time between his native Sligo and London, as The Voice judge juggles commitments in Ireland and in the UK.
"Neither of us has time at the moment, but at the same time, we're not going to leave it too long," he said.
"We're both still young and don't want there to be a huge gap between the kids. We would like Koa to have a little brother or sister to play with."
