Artist and film director Sam Taylor-Wood has married her actor fiance Aaron Johnson.

The couple, who have two children together, tied the knot on Thursday in Somerset, according to a statement issued on their behalf.

Taylor-Wood cast Johnson, who is 23 years her junior, in the John Lennon movie Nowhere Boy, which she directed.

The couple will both take the name Taylor-Johnson.

The bride's gown was designed by Sarah Burton, creative director of Alexander McQueen, who created the dress worn by the Duchess of Cambridge for her wedding last year.

The groom's outfit was a bespoke suit by Tom Ford, the designer-turned-film director.

The actor, whose films include Kick Ass, celebrated his 22nd birthday last week.

He and the Turner-shortlisted artist, who is 45, had their first child together in 2010, while their second, Romy Hero, was born in January this year.

Taylor-Wood has two daughters from her previous marriage to contemporary art dealer and gallery owner Jay Jopling.

The statement added: "There will be no further comment or detail released."
