Westlife superfans across the globe lost their minds when the band announced their reunion in October.
But one Co Down woman was particularly chuffed to hear the news.
Andrea Harper, from Downpatrick, told Belfast Live that she has loved the band since she was wee. She went to her first concert when she was 12.
"I was into Boyzone first, but then when Westlife came on the scene and I was all about them.
"I've been to roughly 30 concerts, at least. For one tour about 12 years ago I went three times in a week. I had all their albums and singles and I've been mad about them nearly all my life," said the mum-of-three.
"I've cried my eyes out at all of them, they're just amazing."
Andrea, now 30, will be among the crowds in Belfast when Westlife perform five nights at the SSE Arena next month.
"I'd love to go to the one in Croke Park as well as the Belfast one, but it's [her daughter] Holly's birthday so I have to miss it. She doesn't realise the sacrifices her mummy has to make."
And if she and boyfriend Matthew ever get married, Andrea says there's no question that Flying Without Wings will be their first dance song -whether he likes it or not.
"Matthew wouldn't have a choice, and he's happy enough. He knows his place when it comes to Westlife."
The superfan admitted that among her vast collection of official Westlife merchandise, she had dolls of all five boys.
"I've only got Shane left," she said.
"It's grand though because Shane's my favourite, he always has been. I don't know what it is about him, he's just gorgeous, isn't he? He really is."
The boy band have said that the Northern Ireland capital is where they have always received the biggest reaction.
"The memories that we have here. I can remember my dad driving me up in the very early days when we started coming to Belfast. Even before we got to play in this arena. Those memories go right back to the very early days of Westlife," said Shane Filan.
"We’ve played a lot of places and Belfast always has a very strong image in our heads of one of our biggest supporters."
