"Oh I’m loving this hair," one fan wrote.

"I literally didn’t recognize you at first," someone else wrote.

"No more Archie, this is KJ," another added.

"I just passed out," a third joked.

"OMG I didn’t think he could get any better," someone else commented.

KJ has started work on One Fast Move alongside Euphoria's Eric Dane, with the film shooting in Atlanta, according to Deadline.

The actor welcomed his first son Sasha Vai Keneti with model girlfriend Clara Berry in September last year and has been sharing sweet glimpses into their life since.

While KJ plays Archie Andrews, one of the most popular redheads in pop culture, he's naturally a brunette and had to dye his hair every two weeks for the role.

"It's pretty gnarly, man," he told Vulture. "I had to go to the salon every two weeks to get it dyed and bleached and stuff. So yeah, it's not my favourite thing to do, but obviously, I've got to do it because the roots keep coming up and my hair grows really fast.

"So, two weeks max I can go shooting, and then I have to get it dyed again. I’m sitting there for at least two-and-a-half hours, so I'm on my iPad and I read some scripts and stuff. I keep myself entertained."

And it wasn't just the actor's hair that needed to be dyed, with KJ describing the process of changing his eyebrow colour as well.

"They ended up bleaching my eyebrows, and I had two holes — they burnt into my skin," he added. "I was like, 'Oh, my, we've got to sort this out.' Luckily, I haven’t had that again, but yeah, it was pretty gnarly."
