A BABY boy has been born four years after his parents died in a car crash.

Shen Jie and his wife Liu Xi, who had been married for two years, were undergoing fertility treatment to have a baby.

But five days before they were scheduled to have one of the fertilised embryos transplanted into Liu they were killed in a crash in the Chinese coastal province of Jiangsu.

Their grieving parents, the boy’s grandparents, filed four lawsuits in three years to gain custody of the couple’s fertilised embryos.

They finally won custody of the embryos in January 2017 and hired a surrogate to carry them, according to The Guardian.

The baby boy, known only by his nickname Tiantian, was born in December last year at a hospital in Guangzhou, more than four years after his parents died in March 2013.

Liu Xi’s mother Hu Xingxian said: “He’s always smiling. His eyes are like my daughters, but he looks more like his dad overall.”

Shen Xinnan, the father of Shen Jie, plans to tell the boy what happened to his parents when he is older but for now will tell him they are living overseas.

Surrogacy is illegal in China so his grandparents had to seek medical help overseas.

It is believed to be the first case of grandparents inheriting their children’s embryos.

After Tiantian was born the legal problems continued as his grandparents were forced to take DNA tests to prove their relationship to him and keep custody.
