Tom Mann was left distraught after his fiancée Danielle Hampson passed away unexpectedly on their wedding day.

Mann, who competed on the show in 2014 with the band Stereo Kicks, broke the awful news on Instagram.

Mann shared a photo of Hampson with the couple’s eight-month-old son, Bowie, and said that she had died early Saturday morning.

“The happiest day of our lives ended in irreparable sadness.

“I feel as though I have wept an ocean. We never made it to the altar, exchanged vows, or danced our first dance, but I want you to know, Danielle, that you were my entire world and the best thing that ever happened to me.

The musician vowed to wear his wedding ring as a symbol of his “unconditional love” for his fiancée, adding that he would muster the fortitude to raise their child.

“I won’t detract from the father you’ve already been, but I swear I’ll do everything I can to raise Bowie the way we’ve always desired,” he stated.

“I assure you he will recognize how remarkable his mother was. I promise to make you so incredibly proud.”

“The most gorgeous individual within and without. The most extraordinary spirit. “We have lost such a remarkable individual,” Mann said.

“Without you, my dearest Dani, the brightest light in any room, my world is nothing but darkness. I shall always miss you.”

Friends from the music industry went to pay their respects, and Lewis Capaldi remarked, “Love you, brother.”

Ellie Goulding wrote, “I’m constantly thinking of you… You are extremely powerful. Always available to you. Love you xxxx”

The singer Gabrielle Aplin commented, “Oh Tom, I am so heartbroken for you and your family. I am so sorry. Sending you and your son a tremendous amount of love and strength xxx”
