Girls Aloud have added an extra show at Dublin's 3Arena next summer.
Tickets for the band's date on Saturday 18 May have sold out, and now the girl group have added a date on Friday 17 May 2024.
Tickets are on sale now via Ticketmaster.
The band, who this month celebrate 21 years since they formed, are also set to take to the stage at Belfast's SSE Arena on Monday 20 May 2024.
Last month, the group, consisting of Cheryl, Nicola Roberts, Nadine Coyle and Kimberley Walsh, announced that they would be embarking on a tour in Ireland and the UK in memory of their late bandmate Sarah Harding.
Harding died in 2021 at the age of 39 after revealing she had breast cancer which had spread to other parts of her body.
In a post to social media, the band said the tour would be a "celebration of Sarah, our music & our incredible fans".
The 2024 tour will feature the band's hits such as Sound Of The Underground, The Promise, Biology and Love Machine.
In 2022, the band were voted the winners of Popstars: The Rivals and formed the all-conquering legendary pop band Girls Aloud.
Cheryl said of the upcoming dates: "We all started talking about the possibility of doing something to celebrate Girls Aloud’s 20-year anniversary a few years ago. The anniversary seemed like an obvious thing that we would celebrate.
"But when Sarah fell ill all priorities changed. She passed away a year before the anniversary and it just didn’t feel right, it felt too soon. But now, I think there is an energy that does make it feel right.
"It’s the right time to celebrate Sarah, it’s the right time to celebrate the band and the right time to celebrate the fact we can still do this 21 years later. That’s a big honour in lots of ways."
