Australian model Samantha Harris is facing the prospect of four years without her future husband after he was jailed for his part in a fatal car accident.

Harris' fiance Luke Hunt, 28, has been sentenced to four years behind bars for hitting and killing a 78-year-old man in Sydney, Australia in 2012 while driving through the city with his famous lover.

He pleaded guilty to dangerous driving causing death and was handed a four-year prison sentence and a six-and-a-half year road ban on Wednesday (14May14).

Harris, 23, was not in court in Sydney for the sentencing.
