Brian McFadden would definitely be a part of a Westlife reunion.
Brian McFadden
The 35-year-old singer - who quit the group in 2004 - thinks his former band "might" get back together one day, and he'd love to be involved if he's asked.
Asked if he thinks the group - who disbanded in 2012 - will reunite one day, he said: "The four guys might get back together... Everyone has so much going on in their lives, the conversation never happened.
"If I was invited, of course I would [be a part of it]."
However, for now Brian is focused on his Boyzlife joint tour with Boyzone singer Keith Duffy.
He told New magazine: "Right now, all me and Keith are focusing on is this show, and we're so excited.
"It's been a long time since we've received calls telling us our tour has sold out in five minutes."
Though they're excited about working together, Keith and Brian don't think it would be a good idea for Westlife and Boyzone to form a supergroup.
Keith said: "I have no doubt Westlife will do a reunion. It would be bad business for them to do a reunion with Boyzone.
"They need to do their first reunion on their own."
Brian added: "Everyone keeps talking about it but you've got nine people you've got to get together. We're not kids any more, driving around in a van."
