Britain's Got Talent judge Simon Cowell gave his first 'golden buzzer' last night to the father-and-son singers from Norwich.
They have since received a huge outpouring of support and congratulations, with Mr Cowell even suggesting the pair will win the talent show.
Tweeting last night, Jack and Tim wrote 'OMG! Thank you everyone so much! Jack and I are literally overwhelmed...I promise to respond but my phone has melted! Jack said 'Dad I think we broke the internet!''
The pair also received many congratulations from residents from their home in Norfolk when readers commented on our story via Facebook:
Christine Frederick wrote 'wonderful, and the song gave me goosebumps.'
James Morgan said 'they were excellent. I was so pleased when Simon pressed the golden buzzer.'
Sarah Mackie wrote 'thought they were fab. Well done.'
Angie Ives said 'Jack was brilliant on The Voice Kids last year! He's just awesome!'
Patricia Owen Wooden wrote 'absolutely fantastic well deserved golden buzzer congratulations. Thank you Simon Cowell.'
Twelve-year-old Jack has previously appeared on The Voice Kids where he made it to the semi-finals of the competition. He also performed in Andrew Lloyd Webbers West End adaption of School of Rock last year, taking on the role of Zack Mooneyham.
The talented pair will now go through to the live shows, meaning they do not have to endure the judges vote.
Britain's Got Talent continues next Saturday at 8pm.
