It's a back to front love story set to be turned into a film.

Aminah Hart had a child as a single mum using anonymous donor sperm but she became curious about the identity of her daughter's dad and decided to track him down.

The story of how she met, fell in love and married her anonymous sperm donor is all detailed in her memoir How I Met Your Father and a film is also in the works.

Aminah told Up All Night's Rhod Sharp her daughter and husband are "dopplegangers" and he "fell in love instantly" with his daughter when they eventually met.
