Who could even think of resisting that face?
"I was bullied by a few people who were much older than me," Liam told Seventeen.
"So I went to camp to learn how to box. I was 12 and my coach was 24.
"It gave me confidence to know that if I could fight him, I could stand up to anyone."
Now that he's all famous, we'd imagine Liam gets more stick than ever, but apparently he doesn't let it bother him any more.
"When I changed my hair, there were a load of people saying they hated it," he told Top of the Pops.
"Obviously, we all want to please the fans - that's one of the mean things - but we are who we are and we can't change that!
"People will either love it or hate it!"
We think he's got some pretty wise words, but what do you think about Liam's attitude to bullies?
