Westlife will play an intimate gig in Belfast next month and fans can now register for their chance to win free tickets.
The band, comprising Shane Filan, Markus Feehily, Kian Egan, and Nicky Byrne, are the last act to join BBC Northern Ireland's summer concert series.
BBC Radio 2 is celebrating the return of live music by putting on a series of gigs around the country.
Westlife will play to a small room of fans on Thursday August 26 in a central Belfast location that has yet to be announced.
The band said: "We are thrilled to be taking part in this year's Radio 2 Live. Our show at Hyde Park in 2019 was such a highlight for us and we can’t wait to do something a little different this time."

Head of BBC Radio 2 Helen Thomas said: "New for 2021 and beyond, Radio 2 Live will take the spirit of our very special radio station around the UK. We’re thrilled to be bringing Texas, Steps, Manic Street Preachers and Westlife to Radio 2 listeners around the country after so long without live music."
Head of Music for BBC Radio 2 Jeff Smith commented: "Radio 2 is committed to bringing live music performance to its listeners as we know how much they love to listen and watch their favourite artists perform the songs they adore.
"Over the past year, Radio 2 House Music has done a brilliant job with performances from Joan Armatrading, Kelly Clarkson, Rag’n’Bone Man and many more, but now it’s time to get back to live performance in front of an audience. Radio 2 Live is going to feature incredible sets from major artists, in front of what I’m sure will be a very excited audience of Radio 2 listeners."
Although capacity is limited, the sets will also be available to watch on BBC iPlayer and BBC Sounds from September 11, with a special highlights show on Radio 2 from 7pm and 9pm the following evening.
Tickets will be allocated via a ballot following registration at bbc.co.uk/radio2live.
