Paul McCartney, the former Beatle’s singer, has popped the question to his girlfriend of four years, Nancy Shevell. He sealed the deal with a grand sparkler.

Sources have estimated the cost of the diamond to be around $650,000. We genuinely wish the couple the best and hope third times’ the charm for Paul McCartney.
