When London woman Aminah Hart turned 42-years-old, she realized that she wanted to have a baby. As she was single at the time, she opted to try In Vitro Fertilization - a process whereby a prospective mother's egg is fertilized by sperm outside of the body. The sperm used in IVF is often provided by an anonymous donor - such was the case in Hart's experience.

During the selection process, Hart was presented with three application forms. Aside from medical information, candidates were allotted a small section to write a little about themselves. The London woman said that one applicant's bio, in particular, stood out to her, according to ABC Australia.

Nine months after choosing her mysterious donor, Hart's beautiful little daughter, Leila, was born. Brimming with pride at her new bundle of joy in the world, she couldn't help but wonder who her little girl's father was.

The new mom decided to stick to the rules and go through the IVF registry - where it's possible to anonymously contact donors with a thank you letter and photographs.

"I just sent him an email of thanks, really from the bottom of my heart," Hart told ABC Australia.

Across the globe - over 9,000 miles away - Scott Andersen, an Australian cattle farmer and father of four, received the messages which would change his life forever. Under no obligation to reply, he did, he thought that Leila was "gorgeous."

Andersen told Hart of how their daughter sharply resembled his other four kids from previous marriages and he decided he wanted to meet her.

For six months Hart and Andersen kept in touch via email. Then one day, just a few days before their daughter's first birthday, Hart got on an Australia-bound plane from London with Leila to finally meet face-to-face.

Following a positive first meeting, the two decided to get together with Leila once every few weeks. Andersen was fantastic with his daughter, and it was only a matter of time before the little tike's parents' relationship blossomed, too.

"Those two fell in love with each other, honestly," Hart told ABC Australia of Leila and her daddy's immediate bond.

Before Hart knew it, the pieces of the puzzle all came together. One night Andersen ran out to grab some milk and came home with an engagement ring and proposed - Hart said yes, and they have been together ever since.

Hart has written a book, "How I Met Your Father," detailing the family's incredibly unique story and it's set to become a movie.
