'X Factor' star Tom Mann reflects on the tragic loss of his fiancée on their wedding day

On the one-year anniversary of Dani Hampson's tragic death, Tom Mann took a moment to pay homage to his late fiancée. 

In a heartfelt Instagram post on Sunday, the 29-year-old former X Factor contestant honored Hampson, who passed away on their wedding day last June.

Captioning a photo of Dani and their 20-month-old son Bowie, Mann expressed his disbelief at the passing of one year.

"1 year, somehow," Mann captioned a photo of Dani and their son Bowie, 20 months. "1 year ago, I put on my suit expecting to meet you at that town hall & tell you ‘I do'. I ended up wearing it in a hospital waiting room."

Mann went on to recall, "1 year ago, my biggest worry had been that unbearable heat. It was impossible to know the unbearable pain that was about to come. 1 year ago, I had woken up beside you for the last time. No answers to how or why, and no words to articulate any of these feelings. Nothing makes any sense & everything has changed. I don't know why you couldn't stay."

"Dan, Bowie will know everything that you were to everyone that knew you. He will know your love & light over your loss," he concluded.

"I am so very grateful that someone as special as you chose me. Thank you for letting me love you."

Originally planning to marry in August 2020, Mann and Hampson had to postpone their ceremony twice due to the COVID-19 pandemic.
