After months of speculation, Sir Paul McCartney and Nancy Shevell have officially tied the knot in London today on what would have been John Lennon's 71st birthday.
The couple, who got engaged in May of this year, first brought their romance to light in 2007 after being spotted at a South Fork sushi spot.
ET has learned that Paul's daughter Stella designed the wardrobe for the groom, 69, outfitting the former Beatle in a navy blue suit. Stella also designed shoes for her new step-mother, 51.
The bride wore a flower in her hair and a long-sleeved, ivory dress that reached down to her knees.
This marks McCartney's third marriage, having wed Linda Eastman and Heather Mills prior, and Shevell's second.
