Britain's Princes William and Harry are set to perform with Take That for this summer's Concert for Diana. The princes are in talks with the reformed boyband to join them on stage for the memorial show at London's Wembley Stadium on July 1.
Singer Howard Donald, 38, told Britain's The People newspaper: "We are inviting them on stage to join in our performance.
"We know their mom Princess Diana loved us so it will be cool for them to do it."
The royal brothers - who will perform alongside Howard, Gary Barlow, Jason Orange, Mark Owen and former bandmate Robbie Williams, who is reuniting with his old group especially for the occasion - are already said to be hard at work practicing their dance moves.
A source said: "The whole thing has been kept very hush-hush. But it will be tremendous thrill for the boys.
"They want to get it spot on as a fitting tribute to their mother. The demands of their Army careers mean they are both extremely fit. So in that respect they will have no problems coping with the high-energy dancing.
"But they are also considering joining in with a chorus of one of Take That's hits - and that is something they are really nervous about.
"Dancing is no problem - they both love hitting the floor in clubs. But singing is entirely unchartered territory for them. They just want the whole concert to go perfectly and make it something their mother would have been proud."
The concert - held on what would have been Diana's 46th birthday - marks the 10th anniversary of the princess' tragic death in August 31, 1997. Other acts confirmed for the tribute show include Lily Allen, Rod Stewart and Sir Elton John.
