Westlife singer Mark Feehily announced that he and his partner are set to become fathers to a baby girl during the band's second gig in Croke Park on Saturday night.
In May, the singer and his fiancé Cailean O'Neill revealed that they were set to welcome their first child later this year.
An emotional Feehily told the crowd at Westlife's second sold-out Croke Park gig on Saturday that they would be welcoming a daughter, saying: "That's an exclusive."

He also added that he "can't wait for her to grow up in this wonderful country".
The crowd cheered and applauded at the happy news.
The group's second Croke Park gig during their highly-anticipated comeback tour was just as electric as the first on Friday night. The concert was also live-streamed in cinemas around Ireland and the UK.
The band, who formed in 1998 before splitting up in 2012, performed all 14 of their No.1 hits during the Croke Park stop of their The Twenty Tour, as well as brand new tracks Hello My Love and Better Man.
Support act James Arthur took to Twitter after the concert to say what an "honour and a truly great experience" it was to play ahead of the band.
He wrote: "I am blown away by your show, one of the best I've ever seen", while praising the "incredible" crowd.
