X Factor singer Tom Mann has been left devastated after his fiancee Dani died suddenly on their wedding day.

Tom, who appeared on the X Factor singing show in 2014, announced the sad news of his partner’s death on social media.

The couple share an eight-month-old son together.

He wrote in a heart-breaking post that he had lost the “love of his life” on what should have been the happiest day of their lives.

Tom declared that his fiancee was the “best thing to have ever happened” to him and that he would continue to wear his engagement ring as a “sign of unconditional love” for her.

He added that he will raise their son as a single dad and hopes he will make her proud.

He 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, 18th June.

On 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 dance 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 to 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 had 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 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.”
