Sian Gomersall and Tricia Imrie will perform with the Proms Military Wives Choir in a sell-out concert to mark the 100th anniversary of the First World War next month.
Mrs Gomersall said: "We are delighted to be performing in the Proms Military Wives Choir and are honoured to be part of this very special event.
"It's really appropriate that the concert will also remember the role that women and music played during the First World War."
Mrs Imrie added that she hoped they would do their husbands proud.
The 100-strong Proms Military Wives Choir is made up of singers from 42 military wives choirs.
The event, which forms part of the BBC's annual Proms series, will take place on Sunday, August 3.
It will also feature life-size puppets from the National Theatre's production of War Horse by Michael Morpurgo.
