Dame Shirley Bassey and Charlotte Church will top the bill at this year's Royal Variety Performance in Cardiff.
Dame Shirley Bassey has criticised Charlotte Church's drinking
The Welsh superstars will perform for The Queen and the Duke of Edinburgh at the Wales Millennium Centre next month.
It will come four months after Dame Shirley said Church had "let herself down" by binge drinking.
They will be joined on the bill by Sir Cliff Richard - 46 years after his first Royal Variety Performance - plus Will Young, Il Divo and Bryn Terfel.
Another Welsh singer, Katherine Jenkins, will also appear, as will Italian tenor Andrea Bocelli and pop group McFly.
Comedians taking the stage will include Catherine Tate and Joe Pasquale.
The performance will take place on 21 November and will raise money for the Entertainment Artistes' Benevolent Fund.
"We are thrilled to be bringing the Royal Variety Show to Cardiff for the first time in such a spectacular fashion," the Fund's life president Laurie Mansfield said.
"This promises to be one of the great nights in entertainment, both in the theatre and on television."
