Actress Natascha McElhone is in mourning following the sudden death of her husband, plastic surgeon Martin Kelly.
The 42-year-old was found slumped on the doorstep of the couple's London home on Tuesday night. He is thought to have suffered a heart attack.
McElhone, 36, who is pregnant with their third child together, was filming in Los Angeles at the time, and left to return to the UK on Wednesday.
The tragic news comes just one day after the couple celebrated their 10th wedding anniversary.
A representative for the actress has stated there would be "no comment at this time".
However, McElhone's stepfather, Roy Gleenslade, has paid tribute to Kelly.
He says: "He was a truly magnificent man as a surgeon, as a father and as a husband. As well as being a brilliant doctor, he painted, wrote his own music, as well as being a great sportsman. He was a true Renaissance man."
British authorities at Scotland Yard are treating the death as unexplained, and a post mortem examination will be carried out later this week.
Kelly was one of the UK's top cosmetic surgeons, and had earned himself the title of 'king of rhinoplasty' for his skilful work.
The couple has two young children - Theodore, eight, and Otis, five.
