Stylish in a white maxi dress and barefoot for their ocean-side stroll the mystery brunette seemed perfectly in sync with the British film director, who was keeping it cool and casual in T-shirt and jeans.
Life is looking good all on fronts for Guy, who wrapped work on his film Sherlock Holmes earlier this year. Currently living the bachelor life, the attractive 40-year-old has enjoyed dinner dates with supermodel Elle Macpherson and socialite Jemima Khan in the last few months.
His career isn't doing too badly either. With Robert Downey Jnr and Jude Law headlining Sherlock, the film is seen as a potential Christmas blockbuster.
The director's name is also being linked to a remake of classic 1955 musical Guys And Dolls. Hollywood bosses are reportedly eager to sign Guy for the project and have given him the go ahead to begin casting the roles played by Marlon Brando and Frank Sinatra in the original.
“Guy has had a lot of meetings with top studio bosses about other projects, but the Guys And Dolls idea really tickled him," revealed a source close to the director.
“He is torn between keeping the script true to the original in New York and taking it to familiar surroundings in London.”
