Your wedding is most probably the most memorable day of your life. It’s all about you!

But what happens if something threatens to overshadow it?

Irish bride-to-be Celé Brits is due to get married on the same date (May 19) as Prince Harry and Meghan Markle. Bummer, right? That’s not the worst of it - her wedding venue is literally down the road from Windsor Castle.

But, wait, there’s more. She’s due to say her “I dos” at exactly the same time as Prince Harry and Markle.

The Irish Mirror first broke the story, reporting that Cape Town-born Brits has a dozen wedding guests scheduled to make their way from Co Kerry, a county in Ireland, to London for her big day.

Their biggest headache will probably be getting through the throngs of royal fans as there is reported to be up to 100 000 onlookers along the route. Her wedding party will also need special security permits to be in the same area on the day.

So what does a woman in her predicament do? Ask Queen Elizabeth for help, of course.

Chatting to Radio Kerry, her mother Jeanne Brits said she had written to the queen for advice. She said: "‘It’s great fun but it’s a worry too."

Jeanne said she wrote to her wishing the royal couple well, but also voiced her concerns for her daughter’s big day.

Jeanne, who has been tasked with taking care of the flowers and wedding cake, was told that she needs to start her journey in the early hours of the morning to ensure she makes it to the venue in time.

But bride Celé doesn’t seem too perturbed by the situation, and is taking it all in her stride, as her Facebook posts suggest.

As to the queen’s response? We’ll have to wait and see.
