Well, this turned around quickly.

Just five days ago Charlie Puth and Bella Thorne were kissing each other on a Miami beach, and now… well, now they're fighting on Twitter.

When they were spotted kissing everyone thought they were an item, but then Charlie started tweeting out apologies last night and Bella posted a photo of her ex, Tyler, on Instagram. 

Then Charlie switching from being sorry to being a tad confrontational. And his tweets? They kinda took aim at Bella and accused her of cheating on Tyler.

Of course, Bella isn't one to take that sitting down, so in one simple tweet she shut him down.

Let's hope that the last of 2016's celeb Twitter wars!
