Katy Perry just threw shade at Ariana Grande on Instagram for the most petty reason

And Ariana shaded her right back.

Ariana Grande is a pretty active Instagram user. Girlfriend posts to the 'gram every day, sometimes multiple times a day. And she's not one of those celebrities who lets someone else run her account — she's out here watching the comments roll in and clapping back when it feels right.

Last week, Ariana shut it down when a follower said she was "sick of her ponytail." This round? The 25-year-old had the perfect response when Katy Perry told her to "put her jacket on please just once."

Here, the image in question:

And the exchange between Katy and Ariana:

Ariana simply replied "no" and if that's not a perfect response, we don't know what is.

It's worth noting that Katy and Ariana are on pretty good terms with each other. We think this exchange was more of a joke between friends than actual shade.

As you were…
