Singer Brian McFadden has said he would "never say no" to a Westlife reunion as he joins forces with former Boyzone star Keith Duffy for a two-man nationwide tour.
The pair, who will perform hit songs from both bands, hit back at rumours that former mentor Louis Walsh had not been supportive of the project, saying he was "fully behind it".
But despite naming the show Boyzlife, the duo denied that it marked the formation of a new "super group".
The tour, which McFadden describes as "Piers Morgan's Life Stories with music", will see the duo talking about their careers and personal lives.
"I had dinner with Louis two days ago and he thinks it's a great idea - he's fully behind it," Duffy said.
"Obviously Louis is still managing the broken-up Westlife - but they are only on a break, not broken up - and he's very keen to get them back together. So he has to protect his brand as well."
Duffy added that the former X Factor judge may even have a cameo in the show - with talk of him filming a clip to be played to the audience.
Addressing a possible Westlife reunion in the future, McFadden said: "We will never say no to anything. You never know what's going to happen down the line ..."
"In a word, yes he would," Duffy interrupted.
"Maybe. If it was the right time. Right place," McFadden said.
While Duffy said that there was "potential" for other members of the two groups to join the tour, McFadden said for now it would be a two-man show.
"People are getting confused thinking that with Boyzlife we have started a new supergroup together.
"But this is me and Keith's show. It's called Boyzlife. There's nothing to stop the rest of the guys pairing up and doing it, but for us this was our way."
Duffy described his time in Nineties band Boyzone as a "roller coaster ride".
"To now have settled down, calmed down, got a little bit older and more responsible, we'd like to be able to think back, reminisce and tell the inside track story of how we felt at the time," he said.
"Because when you are on stage, you are polished and know what you are doing. But the reality is underneath that pop star image is a very naive, scared little boy with no idea."
The sell-out tour, in partnership with Hilton Hotels & Resorts, will kick off in London from October 15.
