Joss Stone is said to be �incredibly flattered� after striking up a phone friendship with Prince William.

The heir to the British throne has been speaking to Joss about her upcoming appearance at the Princess Diana memorial concert next month, and the singletons are said to have struck up a strong chemistry.

A source tells the Mirror, �She thinks he's gorgeous and is incredibly flattered.

�She�s 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."

Do you think Joss� trying to tell William something?
