Young Princes, Old Queen to Honor Princess

Royal hotties William and Harry will remember their late mother's birthday with a benefit concert by Sir Elton John, Pharrell Williams, Duran Duran, Joss Stone, and an unfortunate medley of Andrew Lloyd Webber hits.

The "Concert for Diana" will take place in England on July 1, which would have been Diana's 46th birthday. A memorial service will follow on August 31, the tenth anniversary of her death in a Paris tunnel crash. Prince William, the future King of England, joked, "If it works it'll be brilliant, if it doesn't, then we won't be in the country much longer."

William teased that you'd "have to be very good and ask Santa nicely" for tickets to the show, they'll also be available for purchase online, starting tomorrow. Proceeds will benefit two of Diana's favorite charities.
