British R&B star Jay Sean stunned contestants on U.S. TV talent show THE SING-OFF when he joined performers on stage for a rendition of his hit tune DOWN.
Sextet Nota, from Puerto Rica, were crowned the winners of the reality programme on Monday (21Dec09) after wowing judges Nicole Scherzinger, Boyz II Men's Shawn Stockman and singer Ben Folds with their vocal abilities on an a cappella version of Sean's smash hit.
But they were almost left speechless when Sean himself jumped on stage to surprise them during their victory performance.
Sean tells People.com, "When they called me up and said if Nota win, we would love for you to come out, surprise them and sing your song with them, I said, ‘Oh my God, of course I will.'
"But one thing I knew, and I told them, was, ‘Guys, you do realise there’s actually no backing music. They are the music. So if they get surprised, which they will be, they’ll stop singing! There will just be silence!' Luckily, they’re all such pros and they just kicked back in and we had fun."
Nota was awarded a $100,000 (£62,500) prize and a recording contract from Sony BMG for their efforts on the four-episode TV competition.
