Josh Daniel's rendition of Labrinth's "Jealous" during his audition for "The X-Factor UK" brought judge Simon Cowell to tears that he had to leave the show early. At that time, no one knew the reason but it's believed Cowell was reminded of his mother's death through Daniel's song.

Appearing in the lunchtime show "Loose Women," the 55-year-old finally confirms his emotional reaction was attributed to thoughts of his deceased mother.

The video below, taken from his interview with "Loose Women" and shared by YouTube user Best of Britain, shows Simon explaining the reasons for his emotional reaction to Daniel's song. The "X-Factor" mogul was asked if the recent death of his mom, Julie Brett, had anything to do with his tears.

"I mean it was quite near when it all happened," he says, referring to Daniel's audition to "The X-Factor UK" in August, to his mother's death in July.

"I think it was the last audition and I wasn't really expecting what happened and of course the [lyrics] of the song and it was quite difficult because I thought, 'God this is going to be really hard to sit through this. But then you've got to think of him [Daniel] and it's his moment but yes it was very emotional," Simon explains in the video.

Cowell also reminisced about his mother during his appearance on "Loose Women" with his fellow "The X-Factor UK" judges Rita Ora and Nick Grimshaw. In the video, Simon reveals that after his mother's death, it was very hard for him to decide if he should go back to judge "The X-Factor" or not. However, he says he recalled how Julie was such a big fan of the show and realized that his mother would have asked him to "go back to work" if she was still alive.

Grimshaw lends his support to Cowell when he says in the video, "It really goes to show how much a song and a performance can move you and I guess that's why we want to be part of this show because it's those real moments that make it so exciting and honest."

According to Metro UK, Cowell was completely lost for words during Daniel's performance of "Jealous." He tried to remain poised through sips of water but all throughout the song, he was reportedly slowly starting to get upset.

After giving the 21-year-old three yes-es, Cowell finally walked out of the stage looking very sad. A video of Daniel's audition is also shared on the official YouTube page for "The X-Factor UK," which captured Simon wiping away tears while listening to Daniel's song.
