Aaron Chalmers became a household name in England thanks to his appearance on reality television shows.

Now, he’s hoping to make his mark in MMA.

Chalmers takes on Ash Griffiths this Friday at Bellator 200, opening up the Paramount Network main card from the SSE Arena.

Since appearing on the show “Geordie Shore” in 2014, Chalmers has worked his way up the ranks rather quickly. He fought three times last year for BAMMA, winning all three bouts via first round finish.

“This is my biggest challenge to date, but what I’ve done differently this camp is I’ve moved everything to a jiu-jitsu gym so I’m working on my ground game,” Chalmers said. “My wrestling is coming on leaps and bounds. I’m also working with Damien Trainor, the world class Muay Thai coach. He reckons that my jiu-jitsu isn’t at the same level as his but who does he roll with? I roll with top fighters in the world and the country.”

Chalmers started his MMA career with a submission victory over Greg Jenkins. He followed that up with a 30-second knockout of Alex Thompson before finishing Karl Donaldson in just 43 seconds this past December.

“You know what it is, it’s a 50/50 fight but he’s saying he’s going to submit us or knock us out,” Chalmers said. “Let’s just see when we’re standing, trading in the center of the cage who’s still standing at the end one hand raised.”

With three finishes already to his credit, how does Chalmers see his Bellator debuting going? No differently than any of those bouts.

“I guarantee on May 25 I’m going to be going 4-0 with a spectacular knockout,” Chalmers said.

Bellator 200 airs via delay Friday night with Gegard Mousasi challenging Rafael Carvalho for the middleweight title in the main event. The card also features Michael Page vs. David Rickels in another middleweight contest.
