Joe Mullins, who is based in Washington DC, predicts a girl would have brown eyes and black hair - while a boy would have blue eyes and brown hair.
Mr Mullins, who has worked in forensics for 17 years, has previously done mock-up pictures predicting the looks of the Duke and Duchess of Cambridge's children.
He has insisted that his work is highly scientific, taking account of the parents' colouring, predominant genes, outstanding features and complexions. We think he killed it tho... Check out the young harry, lol.
