Tom Mann, an X-Factor star, suffered a tragic loss last weekend as his fiancée died, barely a couple of hours before their wedding.

The heart-wrenching development occurred on Saturday morning, just before the couples could say their “I do's."

According to reports by TMZ, Dani Hampson, the 34-year-old publicist, had no apparent health issues and the cause of her death is still unknown, as we report.

Taking to Instagram, Tom shared an emotional post, where he described Dani as his best friend and everything.

In the lengthy emotional post, Tom wrote:

I can’t believe I am writing these words, but my darling Dani – my best friend, my everything and more, the love of my life – passed away in the early hours of Saturday morning, June 18th.

What was supposed to be the happiest day of our lives ended in irreversible heartbreak. I feel like I have cried an ocean.

We never made it to the alter, or got to say our vows, or danced our first dance, but I know you know that you were my entire world and the best thing that has ever happened to me, Danielle.

I will wear this ring that I was always supposed to wear as a sign of my unconditional love for you.

I am completely broken trying to process this, and I honestly don’t know where to go from here, but I do know I need to use any strength I can muster for our little boy.

I will not be a mark on the parent that you have already become, but I promise I will do my everything to raise Bowie just the way we always wanted.

I promise you, he will know how amazing his mummy was. I promise to make you so proud.

The most beautiful person inside and out. The most incredible soul. We have lost such a special person and I am sure we are about to see an abundant outpouring of love that reflects that.

I will try to find peace in your messages and comments, but right now I am grieving and I will be for a very, very long time.

My darling Dani, the brightest light in any room, my world is nothing but darkness without you. I will miss you forever.
