On 9th October 2011, McCartney and Shevell were married at Old Marylebone Town Hall where his first wedding took place in 1969. The couple attended Yom Kippur synagogue services the day before out of respect for Shevell's Jewish heritage, but did not seek a religious blessing for their union. Upon their marriage, Shevell became Lady McCartney. McCartney wrote the song "My Valentine", from his 2012 album Kisses on the Bottom, about her. She is second cousin to broadcast journalist Barbara Walters.
