Madonna has turned down an invite to perform at the Diana memorial concert in July - because she'll be too busy rehearsing for Live Earth the following week.
Today's Mirror reports that the Queen Of Pop was asked by Andrew Lloyd Webber to reprise her role as Evita for the Wembley concert.
But Live Earth is only six days later, and they asked Madonna first.
A source told the paper: "Live Earth approached Madonna first and she is committed to performing there. It would be extremely hard to rehearse for both gigs at the same time and she wouldn't want to give less than 100 per cent to either"
The Diana Wembley audience won't miss much though, seeing as how 'Evita' was pretty rubbish.
