They were seen having a pint together just hours before filming.
The two drinking pals appeared on ITV’s Judge Rinder to claim maximum damages (£6,100) over a fake dispute about an office refurbishment.
Thousands watched as the pair conned the show out of £5,000 after providing a fake paper trail as evidence.
The pair came up with the idea after they discovered that ITV pay out the cash, not the defendants.
Horner confessed to The Sun: “It was an Oscar-winning performance from start to finish. By the end Judge Rinder was utterly convinced. Me and Paul went on the piss to celebrate afterwards and have split the £5,000”
Brewster added: “I haven’t done anything wrong. I was paid for entertainment and that’s exactly what I gave them. I was paid to act.”
A spokesperson for ITV responded: “If they have defrauded us we will take this up with police.”
