Teenage rap sensation Bars and Melody are hot favourites to win tonight's Britain's Got Talent final.
The musical pair - 15-year-old Charlie Lenehan and 13-year-old Leondre Devries -already have the backing of lead judge Simon Cowell.
The music mogul pressed his golden buzzer to send them straight through to the semi-finals from their first audition.
Bookmakers William Hill make them 6-5 favourites to win ahead of boyband Collabro who are 9-4 and singer Lucy Kay who is 8-1.
The firm's spokesman Rupert Adams said: "It now looks a like a two horse race between Collabro and Bars and Melody.
"The final of BGT is one of the biggest reality TV nights of the year and we will take a six figure sum on the night."
Meanwhile Canadian illusionist Darcy Oake has revealed he suffered sleepless nights as he prepared his act for the final.
He is set to carry out his most dangerous stunt to date in the ITV talent show tonight, he said.
"Because what we're doing in the final is extremely dangerous, we can't exactly rehearse it before the show, so it is either going to work or it's not," he said.
"If it doesn't, it will be bad. It is literally the most dangerous thing I have ever done in my life. I am beyond worried."
He is one of 11 acts who will fight it out to win the show - and a place performing at the Royal Variety Show.
