The British Royal family has once made headlines, and this time, a magazine in the United States had reported claims of a secret daughter by Prince Charles and the late Princess Diana named Sarah.

According to Globe magazine, the late Princess Diana underwent a medical examination at the age of 19 to test her fertility and during the process one of her eggs was fertilised with Prince Charles’s sperm.

This was however done prior to her marriage with Prince Charles.

The samples were believed to have been destroyed after the marriage.

It was however reported that a rogue doctor was said to have kept one sample behind to be implanted into his wife.

The magazine alleged that Sarah is now 33-years-old living in New York.

It added that the Duchess of Cambridge, Kate Middleton, had met Sarah in New York during her recent trip there.

Buckingham Palace has yet to issue any statement on the matter.
