Simon Cowell was seen moved to tears last night when he introduced The X Factor USA's moving Sandy Hook tribute at the beginning of the season's two-part finale.
And, speaking to reporters afterwards, he called the speech "the hardest thing" he's ever had to do on television.
"I would say it was the hardest thing I've ever had to do on TV in my life," People quotes him as saying.
"We made the decision and decided that we were going to introduce it like we did. And then it hits you what you are about to announce and what it is about."
He continued: "I think anybody in my position would have been the same, and I think it was much harder for the singers. For them to have to sing that lyric … it was a miracle they did it, because it really affected them. But it was the right thing to do."
On air, he said on the verge of tears: "Words cannot describe what happened at Sandy Hook Elementary School last week. We're all deeply saddened by the tragedy, and our hearts right now go out to the families.
"You'll always be in our prayers, and you'll always be in our hearts, and this is our tribute to you."
