McCartney and Shevell first met in the summer of 2007 while staying at their respective properties in the Hamptons, PEOPLE previously reported. At the time, a source told PEOPLE the couple was “clearly well-suited, well-matched,” as they both enjoyed quieter social lives.
Months later, the pair were spotted kissing on a walk along the beach in the Hamptons in November, and the following year, McCartney and Shevell took a series of trips together, including to a private island in the Caribbean, on a road trip down Route 66, to a Beatles show in Tel Aviv and to Paris for a fashion show.
By May 2011, McCartney had proposed to Shevell, who showed off the ring at the Met Gala that year, and that October they tied the knot in a simple town hall ceremony in Old Marylebone. Following the union, the couple headed to McCartney’s home for an intimate celebration with loved ones, and included a toast to McCartney’s Beatles bandmate John Lennon on what would have been his 71st birthday.
