A couple about to marry were left shocked after they realized they have known each other their entire lives after an old class photo revealed they attended the same primary school, The Express reports.

According to the report, Lucy Wilson, 26, and her fiancé Lewis Ball, 25, were amazed to make the shocking discovery. They have been together for four years since they began dating back in 2012 but had no clue they've known each other for almost all their lives.

Everything came to light after a chance look at the precious picture showed the couple of Corby, Northants, just a few feet apart in the same class in their early school days at Stanion Primary School.

Ms Wilson said: "We started chatting in a pub but didn't remember each other from school.

"The next day, he messaged me to go on a date on Facebook and it all took off from there."

Mr Ball, who works as a carpet fitter, went on to use the forgotten fact in a special book he used as part of his romantic proposal which took place outside the couple's old school.

He said: "I wanted it to be a special proposal.

"I just wanted to take Lucy to all the places that were special to us and to propose in the place where it all began."

His romantic book said: “In this school are a boy and girl who from the very beginning were destined to be together.

“Little did the two kids in this photo know that one day they would fall head over heels for each other.

“When they were young, they were never an item. In fact, they barely knew the other existed.

“After primary school the two drifted away from each other's lives. It would be many years and a few mistakes before their lives would cross paths again.

“They lived in the same town and would visit the same places. Their families occasionally saw each other but something was not allowing the two to see each other again.

“But don't worry too much. Just remember, this story has a happy ending - because the two will finally meet one day and it will be worth the wait.”

The couple said they have no firm wedding plans yet but they are planning to throw an extravagant engagement party.
