Britain's Got Talent's Calum Scott has credited his sister Jade for his "powerful" performance.
Calum wowed the judges with his voice on last night's show not only winning four yeses but also Simon Cowell's golden buzzer.
"It was amazing, I really mean that, well done," Simon told him. "I've never, ever in all the years I've done this show heard a guy with the talent you've got. The version [of Robyn's Dancing On My Own] was sensational, you're more than a singer, you're an artist and that's why you got that [the golden buzzer]."
However his success came after his sister Jade Scott got four nos from the judges after also singing.
"It was the best day of my life under the worst circumstances," Calum said after his audition at the weekend. "But I think it was why my performance was so powerful. The first thing I said to Jade was, 'I'm sorry' and she told me not to be stupid."
Speaking to the official BGT website over at ITV.com, Calum continued: "I'd have been happy with advice.
"I couldn't believe it when Simon stood up - it was surreal. I'm still shaking. "
Now into the live semi-finals already, Calum revealed: "I am practising already. I just want to make Simon proud."
