Duchess of Cambridge dazzles at star-studded arts event on edge of London Olympics

LONDON - Art was the subject but the Duchess of Cambridge was the star.

Prince William's wife dazzled onlookers Monday as she met Prime Minister David Cameron and dozens of British artists on the fringe of the London Olympics.

Trumpeters heralded her arrival on the Royal Academy of Arts red carpet to mingle with 800 people from the British music, film, arts and entertainment industries.

The duchess tied her long hair back and wore a dove grey dress by Serbian designer Roksanda Ilincic.

Other guests included fashion designer Stella McCartney, film director Terry Gilliam, model Lily Cole and singers Katy B and Roger Daltrey.

Earlier Monday, William and Kate watched his cousin Zara Phillips race in the Olympic eventing horse competition. The royal couple plan to attend more than 30 Olympic events.
