Singer Tom Mann says he is still in shock after his fiance, Danielle Hampson, died three weeks ago on the couples wedding day.

Nearly 3 weeks on from what will always remain the worst day of my life. Still in shock & still no words - my beautiful Dani is an indescribable loss, the former X-Factor star wrote in an Instagram Story Thursday.

The two have a baby boy, named Bowie, who turns 2 in October .

Nothing can be said or done, Mann said, thanking people for the immense amount of love, kindness & support that both he and Hampsons family have received.

In this darkest of times, it is extremely difficult to feel anything other than sadness, let alone gratitude, but we have found glimpses of feeling that union of love that has come from far & wide for our Dani.
