Prince William deftly sidestepped questions about on-again, off-again girlfriend Kate Middleton on Saturday when he and Prince Harry checked out the final preparations for the next day’s Concert for Diana.

The sons of Princess Diana were asked about the invitations reportedly extended to Middleton and Chelsy Davy, Prince Harry’s girlfriend.

Taken aback, William responded, “Er, well. Er. I’ve got lots of friends coming. Everyone’s going to be there on the night and it’s going to be a very good night.”

Harry was quick to admire his brother’s response. To laughter, Harry said, “Really well avoided William, very diplomatic.”

William split from Middleton in April but is said by those close to him to have been going on dates with her again.

The princes were appearing onstage at Wembley Stadium in London with Joss Stone, whom they watched go through a soundcheck of the songs she will perform, her own “You Had Me,” and a cover of Queen’s “Under Pressure.”

Stone told the princes, “Hopefully she would like it. I wanted it to mean something – every song I wanted to mean something to them when they listen to it.”

As they left the stage, Stone gave both princes a hug before launching into a rehearsal of Tina Turner’s “What’s Love Got to Do With It.”

The July 1 concert takes place on the day that would have been Diana’s 46th birthday and also stars her favorites Duran Duran, Supertramp and Elton John, as well as more modern acts like Pharrell Williams, Fergie and Lily Allen.

William, 25, and Harry, 22, were asked what the princess would think about her sons’ efforts. “She would be slightly amazed that we’d actually managed to do this,” William said, before praising the performers and the workers still putting the final touches to the stage.

Earlier, Harry revealed that the princes asked Elton John to sing “Candle in the Wind,” the song he re-worked for a special performance at Diana’s funeral in September 1997.

The concert will air live on VH1 starting at 11 a.m. ET, with highlights showing on NBC at 8 p.m. ET. TV viewers will be tuning in from more than 140 countries around the world.

The princes came up with the idea for the gig late last year and have been instrumental in the planning from the start, including chairing meetings (with Harry in his army fatigues on one occasion).

Says Nick Rhodes of Duran Duran, “They are pulling out all the stops to try to make things happen.”
