Sir Paul McCartney is being comforted over his divorce by a society heiress.

The former Beatle has been spotted �wining and dining� Sabrina Guinness, 52 - who used to date Prince Charles - including a restaurant date in London on Wednesday night.

A friend of the singer hints to The Sun, �It has been difficult, but Paul�s dealt with his divorce with great dignity.

�His friends are desperate to get him to go out and start living again. People like Sabrina are making this possible.�
