Antoine and Charlotte Jaconelli performed together as the final act on Saturday night's BGT launch episode and stunned the judges with their vocal talents.
Simon Cowell compared Antoine's vocals to Pavarotti, while the press have likened the teenage singer to Got Talent sensation Susan Boyle.
Antoine said that he was fully prepared to deal with the attention that the show is expected to bring him, revealing that problems that caused him a breakdown at school in the past would not be repeated.
"I thought long and hard before entering BGT and discussed it with my family. My breakdown was when I was at school. Me and school don't go so well. This, on the other hand, is exactly what I want to do," he said.
"Singing is what I love and doing BGT has been fun and made me happy. My family are very supportive and I'm being well looked after by the team at BGT."
His mum Tracy said: "This is a wonderful experience for Jonathan. It's doing what he loves - singing. It's really bringing out the best in him and helped him to move on from problems in his past. We've been very impressed with the way we've been looked after by the BGT team. There's a lot of support."
Britain's Got Talent continues this Saturday (March 31) at 8pm on ITV1.
