Aslan and Garron Noone are among the Irish artists announced as support acts for Westlife when they bring their "massive pop show" to Dublin's 3Arena in September.
The group, who were honoured on Friday for their record-breaking run of 82 shows at the venue over 25 years, said their upcoming residency will be "a big Irish celebration".
Speaking to Patrick Kielty on RTÉ One’s The Late Late Show, Nicky Byrne said: "We were thinking about how to make things even more special coming back, and obviously the shows are in production - it’s a massive pop show.
"We’ve been on that stage many times, and we’d love people to join us. So we had a look around and spoke to a few people. We have Aslan joining us as official guests for four shows, Biird for four nights as well, and of course Garron Noone will be joining us for four shows. It’s a big Irish celebration."
Sligo-born Shane Filan said he was excited that "every support act is going to be Irish," adding: "There's a local lad, Paddy Keyes from Sligo, who’s going to be doing some of the shows as well, so we’re very happy."
Kian Egan said the group want to support emerging artists trying to get their big break, just as Westlife once benefited from supporting the Backstreet Boys on their Millennium Tour in the late 1990s.
"When we supported the Backstreet Boys back in 1998, I think it was, that's where it all started for us," he said. "We want to be able to give that back to any young Irish artist out there looking for a shot. We’re on the lookout for a few other people," he added.
The band have recently returned from China, where they performed on a TV show that attracted hundreds of millions of viewers.
Filan said it was a big deal for an Irish band to land such a major gig, adding: "It's the Chinese New Year gala TV show - it’s just crazy how big it is. It’s a great honour in China to be invited to do that show, so for us, as an Irish band, going over to perform was huge. A lot of people watched it."
Referring to the popularity of their track My Love, he added: "That track is such a popular song in China because kids are taught English through it when they go to school, which is pretty cool. That song is massive over there because of that, which is great."
