Bevan moved to 8-0 in his professional career on Saturday, beating Martin Bulacio by second-round stoppage in London.
The 25 year old, who won silver at the Commonwealth Games representing Wales, has won all eight of his pro bouts by stoppage.
And the super middleweight brought another strong following with him to the Copper Box Arena, prompting Matchroom’s Hearn to buy a beer for all 200 of his fans.
“It cost me nearly a grand!” promoter Hearn admitted with a smile, speaking to BBC Sport. “It seemed like a good idea at the time.

“I love the fact that all of those guys have travelled to every fight Taylor has had. Sometimes he’s on at 5:30PM, but they still come up from Southampton.
“They’ve been to Manchester, they’ve been to Birmingham, they’ve come to London. Because he’s still learning, those numbers tend to taper off.
“But it’s the same numbers all the time. There are 200-odd on a bus, on a train, and I think it’s unbelievable that they support him.
“We will be in Southampton, and he will headline this year. Those 250 will be a few thousand.”
Bevan was pleased with his mindset as he secured the eighth win of a professional career that only started back in November of 2024.
He believes he is getting better with each fight and was particularly delighted with how quickly he settled into his win over Bulacio.
Bevan made quick work of the Argentinian, finishing him off in the second round with a brutal body shot.
“I’m over the moon with that. It wasn’t what I was expecting, to be honest. I’ve watched a lot of his fights in the build-up to this fight,” he said.
“He is a very tough opponent who has taken some top-quality opponents through the rounds. I was expecting eight rounds tonight.
“Anything more than that would have been a bonus, really. I was happy with my mindset in the ring; I settled into the fight a bit more.
“I’m just getting better as it goes on. In my last fight, I settled into it after three or four rounds. This time, I was settled from the first round.
“The only way is up for me. Hopefully, I can keep improving, and you are only going to see better things.”
On his support, Bevan added: “It means everything to me. It drives me in training, it motivates me. Thanks to everyone for the continued support.
“A big fight in Southampton gets me very excited. It’s something that I dreamt of as a kid, and it will be great to bring a big show to the south coast.”
