The former Beatle, 68, proposed to NYC businesswoman Shevell, 51, two weekends ago "during a romantic candlelit dinner for two," a source recently told Us Weekly. As for the ring? It's estimated to be an impressive $650,000!
This will be the third marriage for the legendary rocker. His first wife, Linda, died of cancer at the age of 56 in 1998; married for 30 years, they had three children together. McCartney's second marriage to Heather Mills in 2002 ended with a messy, expensive divorce in 2008.
McCartney and Shevell began dating in the Hamptons in 2007, while he and Mills were already estranged.
