Keeping up with the Jones sisters . . .

GUESTS at the party of the weekend thought they were seeing double. Financier Ben Goldsmith’s wife, Jemima Jones, 35, left, wore a long, red dress that matched the one sported by the model-turned-caterer’s pregnant sister, Quentin, 38, far left.

‘Not planned, but we’re always a in sync,’ jokes Quentin, who’s married to tech entrepreneur George Northcott.

The party in Paris was to celebrate the 40th birthday of interior designer Hikari Yokoyama, wife of White Cube gallery founder Jay Jopling, 59. Among the guests were James Blunt, 48, above with fashion designer Misha Nonoo, 37, and pop star Ellie Goulding, 35, inset.
