Everyone at Britain's Got Talent found themselves in tears after two unlikely contestants appeared on the show this evening.
Police officer Dave Wardell, from Buntingford, went on stage alone first, before turning to his side and saying: "I've brought a friend along."
But it turned out his 'friend' was of the four-legged variety - his dog, Finn.

"Finn is a nine-year-old German Shepherd. He's been my best friend since he was a puppy," Dave explained, saying they'd both be going home to a plate of steak if they got four yeses on the show.
"Finn has a bit of a cheeky character. He knows how to get exactly what he wants from me - he knows how to pull all my bells and whistles.
"He's one very special dog."
Dave and Finn then wowed judges with a casual bit of mind reading (as you do), with Dave successfully guessing David Walliams' word through the power of his pooch.

But that was only the half of it, as a screen behind them then began to tell their incredible story - which was when the tears began.
You may recognise the duo from when they hit headlines last January, after the heroic dog ended up getting stabbed while protecting handler Dave.
Finn was out with Dave fighting crime when a suspect stabbed the pooch with a 10-inch blade.
Finn was rushed to a 24-hour vet and was eventually moved to a specialist unit, where they managed to save him. The brave pup was given oxygen and morphine and vets attended to the stab wound, which had punctured a lung - the blade missed his heart by a matter of centimetres.

After hearing about their amazing tale, members of the audience - and hosts Ant and Dec - can be seen wiping away tears.
An emotional Simon told Dave: "If I had a golden buzzer left I'd give it to you. When I hear about animal cruelty, especially dogs, it upsets me. A dog will literally give up its life for you.
"Finn's beautiful, I love him."

Unsurprisingly, Dave and Finn got four yeses.
Dave, who has taken the now-retired police dog in to live with him, has since campaigned for Finn's Law, which gives greater legal protection for service animals.
Dave told the Mirror: "There isn't a bigger stage than Britain's Got Talent. Dogs like Finn are out there day and night doing incredible work.

"If I can tell Finn's story, showcase service animals and talk about Finn's law, I've already won.
"My day job is running through gardens at 3am chasing after car thieves, so you can imagine walking out in front of thousands of people in front of four of the most famous people in the land. It was surreal.
Looks like steak's on the menu for Finn!
