The blushing bride, 31, stunned in her $80,000 (£50,000) Valentino couture lace gown, which featured long sleeves and a high neck. She finished off the look with a cathedral length lace veil, while her older sister Paris donned a floor-length blue gown as maid of honour.

The ceremony took place in the Orangery at Kensington Palace, the royal residence of Prince William and his wife Catherine, Duchess of Cambridge, and guests included supermodel Naomi Campbell, actress Kate Beckinsale and former U.S. First Daughter Chelsea Clinton and her husband Marc Mezvinsky, reports

Hilton family friend Lionel Ritchie is said to be performing at the newlyweds' reception.

Rothschild, 30, proposed to Hilton last August (14) after three years of dating.

The marriage is the groom's first and Hilton's second - she was previously wed to Todd Meister, but had the Las Vegas union annulled just three months later.
