Girls Aloud will reportedly split after their latest tour.

The 'Something New' hitmakers are expected to call it quits once their forthcoming reunion UK arena tour is over as they feel their ten-year career together has run its course.

A source told The Sun newspaper: ''The girls have known all along this would be the last time they would all work together. At the press conference to announce the tour, they deliberately dodged questions about future plans because they did not want to spoil the excitement.

''They all felt it wasn't right for them to be singing songs like 'Love Machine' and performing the same as they have when they're in their thirties.

''They all want to make this a way to bow out on a high and walk away for the next chapter in their lives without constant questions about when they will be getting back together.''

Girls Aloud - which is made up of Kimberley Walsh, Nadine Coyle, Cheryl Cole, Nicola Roberts and Sarah Harding - are said to have made a pact to keep the news secret until their 'Ten - The Hits' tour ends.

The split is thought to be orchestrated so the girls - who all have long-term boyfriends - can finally settle down and start families.

Girls Aloud's 'Ten - The Hits' tour starts in Newcastle on February 21 and runs until March 20 when the band will perform in Liverpool.
