Proud Mark Feehily is set to welcome a baby girl.

He and his fiancé Cailean will become dads to a little girl later this year, he has announced. Mark shared the news at last night's Westlife gig in Croke Park. "That's an exclusive," he told the crowd, adding "I can't wait for her to grow up in this wonderful country". Mark appeared on stage with bandmates Nicky Byrne, Kian Egan and Shane Filan for their second night playing in the capital. Thousands of Westlife fans packed out the Dublin stadium on Friday and Saturday night to welcome the boys back after a seven-year hiatus. Mark's announcement came after he revealed in May that he and Cailean were having a baby together. He shared the news on Instagram, saying it was the "proudest moment" of their lives. "It really makes this my most special birthday EVER to let everyone know that later this year we will become Dads for the first time," he captioned a photo of himself and Cailean with an image from their baby scan. "This is the proudest moment of our lives and we are beyond excited to say it out loud!" Mark also revealed this year that he and Cailean are set to get married. After initially keeping their relationship under wraps, he posted an image of himself and Cailean to Instagram, writing "the mystery is no more hehehe."
