The happy couple tied the knot on Sunday (October 9) in London, England.
The 69-year-old Beatles legend first began dating Nancy, a businesswoman, back in the summer of 2007, and the couple were engaged in May.
Coming out to show love for Paul was Beatles drummer Ringo Starr!
FYI: This is Paul‘s third marriage – he married Linda McCartney in 1969 and Heather Mills in 2002.
Congratulations to the happy couple!!
