Paul McCartney and his girlfriend of four years, Nancy Shevell, are engaged to be married.
“Nancy and Paul are getting married,” a source close to Shevell, 51, a New York businesswoman, first told PEOPLE Friday. “Ring and all – very exciting.”
McCartney’s rep later confirmed, but would not provide any more details. The Beatles legend, 68, started dating Shevell in the Hamptons during the summer of 2007, and despite their 17-year age difference, a source close to the couple told PEOPLE they were a perfect pair.
