Just kidding! They aren't!
From this cover photo, you can obviously see that poor Antoni is actually third wheeling during this hockey game date for Pete and Kate.
It seems like our beloved SNL star has moved on rather quickly from Ariana Grande and his relationship with Kate is blooming. They have become so close in this short amount of time that they are comfortable with shoving each other's tongues down their throats in a public setting as seen in other photos from the event.
In recent Instagram posts, we have seen Antoni and Pete's friendship has been growing as well.
For example in this Instagram post by Antoni, the caption reads "Random pic of me and my frahnd no reason at all totes random love you Petey xo"
This was a sweet post to see this interesting duo hanging out together.

In conclusion, these three very different individuals are not in a relationship, but each has their own personal connections to one another.
