UK fans have been left wincing as the new series gets underway. The smash dating show, now airing on E4, returned for another season on Monday (September 16), with fans eager to see what will happen. The series sees a batch of singletons put their trust in science and get hitched to a person they have never met before.

Though the show first aired back in 2015, the show has undergone a slew of changes to make the British series much more like the Australian edition. Ramping up the tension, the show sees the couples meet once a week and watch as the tension amidst the newlyweds spill out on TV. With a new series kicking off, fans were thrilled to see a new set of hopefuls try and find love.

But one particular groom had viewers in shock as he opted to pull off a risky trick as he met his bride at the altar. In the first episode, relationship experts Paul C Brunson, Mel Schilling and Charlene Douglas paired mechanic Kieran Chapman from Newcastle with dog walker Kristina Goodsell from East Sussex. With the couple set to give their vows, fans were horrified as Kieran decided it was a good time to be cheeky.

During what was meant to be a heartfelt moment between the new couple, Kieran put in a pair of fake teeth to prank Kristina as she walked to the altar. When she saw the teeth, bride Kristina didn't seem to be all too impressed, with Kieran promptly taking them out. It appeared that Kristina and Kieran had gotten off on the wrong foot, but sparks were now starting to fly between .
