Sir Paul McCartney has admitted that his acrimonious marriage to Heather Mills was one of the biggest mistakes of his life.
Asked whether the wedding was one of his worst decisions in the last decade, the music legend said that it was a "prime contender".
Sir Paul, who has a six-year-old daughter Beatrice with the ex-model, told Q magazine: "OK, yeah. I suppose that has to be the prime contender. But I don't wanna down anyone.
"These things happen, y'know? But I tend to look at the positive side, which is that I have another beautiful daughter out of it."
The ex-Beatle did not mention Mills, who he wed in 2002 and divorced last year with a £24.3 m settlement, by name.
Despite the bitter marriage, the music legend told the magazine that he had "managed to feel quite fulfilled this decade".
He said that having "a new girlfriend" - wealthy US divorcee Nancy Shevell - was one of the best things about this century, as well as being with his children.
Sir Paul, 67, dismissed reports that he was going to retire, saying: "I have too much fun. Why would I retire? Sit at home and watch telly? No thanks. I'd rather be out playing."
Asked whether he lost £60m in the credit crunch, he replied: "I've no idea man. The thing is ... they make it up."
