It seems Paul McCartney is a firm believer that third time's the charm! He recently got engaged to his girlfriend since 4 years back, 51-year-old heiress Nancy Shevell. His publicist confirmed the happy news yesterday, although reports that he had gotten engaged surfaced already on Friday. We wish him nothing but luck his third time around the altar! We wonder if Paul's designer daughter Stella will be given the honor of designing the wedding dress? That would be so adorable!
