ROYAL JUMPER

Charlotte Casiraghi, 31

DAUGHTER of Monaco’s Princess Caroline and granddaughter of film star Grace Kelly, Charlotte’s wealth is estimated at £4 billion.

She seems most comfortable in riding gear, first taking part in the Longines Global Champions Tour in 2009. While not a professional, she often rides in the Monaco leg, of which she is patron.

After her father died tragically young in a boating accident, her mother tried to keep her out of the public eye (right, with family). Yet today, she is a regular at fashion shows and has been on the cover of French Vogue.
