A Britain's Got Talent singer has hit back at claims he is a professional singer after being recognised by the judges.
Brian moved the judges and go a standing ovation from the audience with his incredible performance of the A Star Is Born track I’ll Never Love Again.
On Saturday night's show, David Walliams admitted he had seen Brian Gilligan in West End rock musical The Commitments.
During an appearance on today's Good Morning Britain, the Irish singer revealed the heartbreaking story behind his decision to audition.
Brian explained how the birth of his son changed his perspective on life after his brother's tragic death and inspired him to audition on BGT.

He said: "I suppose the main reason, the significant reason for me to do the show, I was trying to find a motivation out of a struggle to do something that would be a massive challenge and expose me on a platform in front of four judges to give their opinion.
"I wanted to hear it from them. To go out and perform and not know what the reaction would be from the audience.
"It's psychological boost a boost of confidence, it's given me a different energy and I want to get up and do another round."
Brian spoke about the devastating moment he discovered his 55-year-old brother had died from a heart attack.
He said: "I was in London at the time and got a call from my other brother. It was very quick and instant. It was a moment I had to take a step back and register what had happened."
But he was motivated to get back into singing by the birth of his son, Leo, who is now nine-months-old.
Brian said: "I wanted a challenge and a motivation to get up as a singer and a solo artist specifically to spur myself on because I’ve been struggling with this depression and these up and down feelings.
"Sometimes you wake up and feel great, sometimes you feel down in the dumps.
"You’re quite expose din that way. Your strength is you and you have to get yourself through these performances by yourself."
Brian spoke about his West End past during his audition after being recognised by judge David.
When Simon Cowell asked him about his background in music, Brian explained: “I was very fortunate to have some success in the West End.”
David said: “You were in The Commitments,” to which he replied: “Yes I was, yeah.”
The comedian added: “Fantastic, cause I saw you in it. You were brilliant.”
