Girls Aloud will reunite for a 2024 arena tour in Ireland and the UK in memory of their late bandmate Sarah Harding.
The group will play Dublin's 3Arena on Saturday 18 May, and Belfast's SSE Arena on Monday 20 May 2024.
Nadine Coyle, Cheryl, Nicola Roberts and Kimberley Walsh shared the same video on social media to announce the news.

"A celebration of Sarah, our music & our incredible fans.
"We can't wait to sing & dance with you again."
The tour will kick off in May in Dublin next year, before going to Belfast, Manchester, Cardiff and Newcastle at the end of the month. They will play dates in Aberdeen and Glasgow in June, as well as Nottingham, Leeds and Birmingham.
The band will perform two nights at London's O2 before closing the tour at the Liverpool M&S Bank Arena on 19 June.
Harding died in 2021 at the age of 39 after revealing she had breast cancer which had spread to other parts of her body.
