Geordie Shore store Aaron Chalmers extended his perfect MMA record to 4-0 at Bellator 200 at Wembley Arena in London.
The reality TV personality choked opponent Ash Griffiths inside two minutes of the first round.
Chalmers has now won each of his professional bouts by stoppage, two by knockout and two by submission.
The Joker took a strong knee to the head, which seemed to stun him, but he responded with a huge punch to put his opponent on the canvas.
Chalmers tried to finish the fight on the ground but the referee allowed it to go on, before he picked up Griffiths and choked him out standing up.
"I have been working a lot on my ground game," Chalmers said afterwards.
"I took a knee, it woke us up. Bang. Sit down, son.
"If you don't like it, then f*** you. Simple as that. I have the best team around me in England. Simple.
"That's why I have just put him away in the first round once again."
