AceShowbiz - Zach Bryan apparently is not letting Brianna LaPaglia (Brianna Chickenfry) live peacefully without him. The country music star appeared to have intentionally irritated his former girlfriend with a paid shout-out at a recent UFC fight.

Sharing the details of Zach's paid shout-out was Dave Portnoy, who called out the 28-year-old singer for what he did to Brianna. On Wednesday, November 20, the Barstools Media founder uploaded via Instagram a video, in which he called the artist a "psychopath."

In the short clip, Dave revealed that Zach paid UFC fighter David Onama to give the "Something in the Orange" hitmaker a shout-out during his celebratory speech. Dave said, "I know I said I'm done talking about that small little pathetic man, Zach Bryan, but listen to this story."

Dave went on to recall that Brianna attended David's UFC fight against Roberto Romero on Saturday, November 16, noting that "everyone knows she's going." He then played a video of David's celebratory speech. The fighter said, "I wanna come back here next month to watch Zach Bryan in concert. So, I'll be here for that."

Dave also showed a short clip of Brianna listening to David's speech. It could be seen that she was sitting down on her seat, seemingly looking irritated when David mentioned Zach's name. She tried to keep her eyes off the athlete as she looked around.

Dave further provided a video of David's podcast interview, in which he received a question about being a Zach Bryan fan. In response, David admitted that Zach's team contacted his manager about the paid advertisement. He also claimed that he does not know much about Zach. Instead, he proudly declared that he is a big fan of Morgan Wallen.

Dave additionally slammed Zach for the singer's "embarrassing" move. "This small little 4-foot-8t f**king psychopath is that pathetic and that lost where they gotta beg UFC guys for a shoutout just to try rub it in Bri's face? Like Brianna gives a f**k!" he blatantly said.

"We get you're world famous, but everybody knows you're a f**king piece of s**t loser and now we know how pathetic and small and f**king low you are," he added. "By the way, it's embarrassing. You look like the smallest man who ever lived!"

Dave has been a vocal supporter of his fellow "Barstool Sports" podcast host Brianna since she was dumped by Zach. Dave even showered her with praise for turning down Zach's offer of $12M cash to keep quiet following the split.
