EDEN CONFIDENTIAL: Sir Paul McCartney’s grandson, 24, is enjoying a romance with the 21-year-old daughter of billionaire Bill Gates

Money can’t buy you love, but it does help you mix in some fascinating social circles.

I hear that Bill Gates’ daughter is enjoying a passionate romance with Sir Paul McCartney’s grandson.

Phoebe Gates, 21, whose Microsoft founder father has a fortune of £88 billion, is dating Arthur Donald, 24, the eldest son of photographer Mary McCartney and her first husband, TV producer Alistair Donald. By comparison, Macca is worth a paltry £950m.

Phoebe shared this photo online of her with Arthur, a climate investor in New York, taken on a balcony in Paris.

The two families already enjoy close ties as Arthur’s aunt, the fashion designer Stella McCartney, is good friends with Phoebe’s mother, Melissa Gates.

Prior to Phoebe’s romance with Arthur, she dated fellow Stanford University student Robert Ross

“Even when I was little, she would send me things and little notes and I was so excited,” Phoebe says of Stella. ‘We are really deeply connected.

“I’m my parents’ daughter, that gives me a great privilege, but that’s not what defines me.”

Prior to Phoebe’s romance with Arthur, she dated fellow Stanford University student Robert Ross. She condemned racist comments she received about their interracial relationship.
