As one of the more private couples going on the celebrity circuit, Lara Stone and British comedian David Walliams never fail to look madly in love. We spotted them looking all cute and proud on day four of one of Europe's most famous horse race meetings, the Royal Ascot. Some of the royals attended on the day, including the Queen, but we're dedicating our gallery to Lara and David! We loved her chic knee-length dress and matching headpiece, and her minimalist one-strap black heels and box clutch. David looked very dapper in his top hat and tails — click through to see the happy couple enjoying their day at the races!
