Mark surprised fans at a Westlife concert in July by revealing his baby's gender.
He broke the news that they were expecting a girl at the GAA headquarters on Saturday, RSVP Live reported.
Mark told fans: "That's an exclusive."
The singer spoke of his excitement of his little girl "growing up in this country."

Mark has opted to stay private about his relationship over the last six years, only speaking about his partner on very rare occasions.
In 2017, he explained why he chose to keep his romance under wraps.
Speaking to Mail Online, he said: "He is not quiet believe me, he is far from quiet, but he has no experience whatsoever in the music industry and he is quite shy about coming to the red carpet.
"A lot of people ask me his name and it is not that I don't say his name, it is his thing to say and if he wants to be in a magazine then that's his choice."
While Mark and his partner, who is also Irish, are famously tight-lipped about their relationship, the singer has admitted that they've both been "broody" for years.
