Katy Perry wasn't thrilled with this band of Justin Bieber lookalikes' latest front.

Perry commented on several Instagram photos of Bieber shading him this week, particularly for his hair, which had, prior to this, week grown out into a shaggy bob before he chopped it off.

Responding to a picture of his hair Tuesday, Perry posted a photo of her in a similar pose as Timothee Chalamet, who also just Instagrammed a shot of his new 'do, suggesting that she had a role in him choosing to cut it.

"I knew it wasn't the hair was too clean," Perry commented on Bieber's manager Scooter Braun's Instagram shared Sunday, throwing some shade at Bieber's former long locks.

In Braun's post, he congratulated the pranksters from Yes Theory, the guys behind that supposed Biebervideo with his long hair while eating a burrito from the middle section out to the ends.

"Well done to the @yestheory guys... but you can never prank a prankster... as for everyone else...#itisnotJustin," Braun captioned the video, reposting it.
