Lady Diana a huge Freddie Mercury fan. Read more for details. PRINCE William has been secretly calling singer Joss Stone ahead of his late mum's memorial concert.
Wills, 24, wants the 20-year-old soul superstar to steal the show on July 1 by covering songs by Princess Diana's favourite artists.
The pair have spoken on a number of occasions about the Wembley Stadium concert - on what would have been Di's 46th birthday - and have since struck up a close friendship.

Wills, who broke up with Kate Middleton, 24, in April and Joss are both single.
An insider added: "Joss is delighted by the fact that Wills is phoning her and they hit it off instantly. They've spent ages talking about which songs she should perform and have painstakingly gone through a list of Diana's most loved artists. They've settled on Queen and Tina Turner and Joss is incredibly honoured to be asked to perform them."
The prince has asked Joss to sing Queen classic Under Pressure because his mum was a massive fan of Freddie Mercury. She will also belt out a Tina Turner number, as well as her own hit song You Had Me.
Joss, who is No2 in the album charts, has told close pals that the show will be one of the highlights of her career.
She said: "I loved Diana and all that she stood for - it really is a pleasure to be involved and help out Will." Joss hasn't had much recent success with men.
Her ex Beau Dozier sold a story about their 10-month relationship. She said recently: "I think I'll have to turn lesbian. Every girl my age wants to be in a relationship. I haven't had one in two years and look how that ended."
Wills and brother Harry, 22, have also lined up stars including Elton John, Duran Duran, Bryan Ferry, Rod Stewart, P Diddy and Lily Allen for the five-hour concert which will be shown in 140 countries.
