UPDATE 10:09 AM PT — According to the Ellis County Wild Game Dinner organization, the guitar was donated to the auction before Taylor Swift ever made her Kamala Harris endorsement.

A certificate of authenticity confirms Taylor did sign the instrument, which was donated to the auction by a third party. The donation was not intended for destruction … but the buyer paid for the item and chose to smash it up himself.

The Ellis County Wild Game Dinner is a non-profit supporting agricultural education for local youth, and the money went to a good cause.

There was a whole load of teardrops on one of Taylor Swift’s old guitars — after a man bought her prized instrument at auction … only to immediately smash it to smithereens!

The footage is going absolutely viral, showing a white-haired dude grabbing a hammer and going full demolition mode on the autographed guitar — after dropping $4,000 on the instrument.

You can hear him giggling like a kid in a candy store, totally relishing the chaos. At one point, it looked like he was about to raise the guitar over his head to smash it to the ground … before the host snapped him back to reality.

The video started blowing up Monday — the scene appears to be from an event called the Ellis County Wild Game Dinner held outside Dallas, Texas Sunday night.

People are speculating it might be tied to politics — especially since Taylor recently endorsed Kamala Harris for president.

The man’s antics have sparked a major debate online … with some cheering him on and others saying he could’ve spent that cash in way better ways.
