Brianna LaPaglia threatens to release alleged abuse tape of Zach Bryan

Brianna LaPaglia‘s not playing when it comes to her cat … says if Zach Bryan sharing more photos of the animal, she will release a tape she claims shows him throwing objects at her.

The Barstool Sports personality took to TikTok Sunday morning … saying that if he — apparently referring to Bryan — keeps posting pictures and videos of his cat, she’ll share a clip of him “whipping the s**t * to my face.”

You’ll want to watch the video … BL seems pretty serious about this — though it’s hard to tell whether or not she actually has a clip of the alleged act tucked away somewhere.

Brianna’s boss Dave Portnoy wants her to drop the alleged video … and tells her to post it — though LaPaglia promises to send it directly to him instead.

We don’t do that. We’ve reached out to Zach about Brianna’s claim … so far, no word back.

Of course, Brianna and Zach’s split has been full of drama … with Brianna claiming that Zach tried to pay her millions to sign an NDA after he emotionally abused her throughout their relationship. Bryan has not responded to any of these accusations either.
