British actress Natascha McElhone has paid tribute to her late husband with a memorial service exactly a year after he died of a heart attack.

The Californication star was filming in Los Angeles when her plastic surgeon partner Martin Kelly suffered a cardiac arrest on May 20th last year, collapsing on the doorstep of the couple's home in London. McElhone, who was pregnant with the pair's third child at the time of Kelly's death, attended an emotional remembrance ceremony in London on Wednesday.

Family and friends of the couple gathered at the Royal Society of Medicine in the British capital to commemorate Kelly's life. The couple's eldest son, nine-year-old Theo, paid tribute to his late father in a short speech, describing him as "a boy inside a man."

McElhone and Kelly's family also includes Otis, six, and baby Rex, who was born five months after Kelly passed away.
