The lads were on The Late Show with Stephen Colbert last night and it seemed like a good opportunity for frontman Alex Turner to show off his new do.
His hair has been making headlines for the last year, with some fans even setting up a petition for him to lop it off along with the beard.
Well, they got their wish.
In all fairness it looks great and light but himself and BFF Miles Kane have morphed into one person...Alex Kane.
We'd give it a four out of five.
And that's unheard of.
Woah, check out the haircut on #AlexTurner! @ArcticMonkeys fans, what do you think??
Tune in to #LSSC tonight to see #ArcticMonkeys perform ‘The Ultracheese’ 🎸 pic.twitter.com/L3zQhjIwtH
