The One Show presenter Alex Jones said the TV show's team is "devastated" following the death of a colleague at the weekend.
Paying a touching tribute to researcher Charlie Mott on Monday evening's show, Welsh host Alex send her love and thoughts to his family and loved ones.
Mr Mott was a senior researcher on the BBC show, and an assistant producer with the channel.
The cause of his death is yet to be publicly confirmed.
Alex, 43, signed off the show by saying: "Now before we go, we just want to pay tribute to one of our colleagues Charlie Mott who sadly died at the weekend.
"Everyone on the team is absolutely devastated, he was a huge talent and such good company.
"We miss him so much. Our thoughts are with his family and we are sending lots of love from all of us here. Goodnight."
The show then ended without the usual credit music, instead in silence.
Viewers took to Twitter following the news to pay tribute, as those who knew him did the same.
A colleague said: "There are no words. We love you so much Charlie."
Another added: "Will miss you buddy x."
The One Show airs weeknights at 7pm on BBC One.
