All you need is love... and a big fancy castle. Former Beatle Sir Paul McCartney, 59, married fiancée Heather Mills, 34, today in a $3 million ceremony at Ireland's Castle Leslie. "Ten people at the wedding you have heard of and the rest will be family and friends," McCartney told reporters on Monday. Among the 10 celebs reportedly in attendance: Ringo Starr, Eric Clapton, Sir Elton John and Pink Floyd frontman David Gilmour. The menu was strictly vegetarian and the dress code, casual. There was lots of rock and roll music, too.
