Brianna Chickenfry’s best friend Grace O’Malley has slammed her ex-boyfriend Zach Bryan one month after their messy split.

The media personality appeared on the reality show UpDating, where she did not mince words about Bryan, 28, who blindsided Brianna, 25, in October when he announced that they had broken up.

While talking about her dating life with hosts Brandon Berman and Harrison Forman, O’Malley said men on dating apps are most interested in talking about her boss, Barstool’s Dave Portnoy, and ‘other people.’

After she was asked to specify what other people she was referring to, someone in the audience shouted out the country singer’s name.

‘F*** that motherf***er,’ Grace swiftly answered. 

Elsewhere in the discussion, she stated in regards to Bryan: ‘I don’t f*** with a hick with a vendetta.’

Brianna, whose last name is LaPaglia, has sworn off men in the weeks since her breakup, despite recently appearing in a social media post with a mystery guy.

Responding to rumors that she has moved on to another romance, she reacted in a TikTok video: ‘I’m hanging out with a guy who’s going back to Australia; I’m never going to see him again. Am I not allowed to live a little? Am I not allowed to smooch a little?’

The star also said she is in ‘intensive therapy’ in the aftermath of her public falling out with Zach. 

‘I’m married to my career. I’m never dating anyone ever again,’ she told Page Six at the Formula 1 Las Vegas Grand Prix.

Instead, she said she is focused on writing a book: ‘I’m writing a lot. I’m really excited. I have a book, and we’ll see. We’re coming out. We’re doing a lot of stuff.’

‘No love given is love lost,’ she reflected, adding, ‘Sometimes you get stuck with a bad guy, but that doesn’t mean that there aren’t good men out there. I’ve dated really good men.’

Earlier this month the podcaster alleged that Zach, who she dated for a year, had been cheating on her throughout the relationship.

‘Fun fact my biggest celeb crush tried to slide a few months ago but of course I denied bc I had a bf and I was getting cheated on the whole time hahahhahaa,’ she wrote in a caption to her 2.1 million TikTok followers.

In the weeks after their split, Brianna shared more details about the doomed relationship, including accusing Bryan of taking her cat out of spite and being emotionally abusive.

The influencer also claimed that the music artist offered her millions of dollars to keep quiet about their connection.

‘The last year of my life has been the hardest year of my life, dealing with the abuse from this dude,’ she said on a November 7 episode of her BFFS podcast.

‘I’m still scared of him. My brain’s rewired. I’m scared to make him mad. Last week I didn’t want to talk about it because I was scared,’ she explained to listeners.

She continued, ‘I still said f*** your money,’ in reference to an NDA she alleged Zach urged her to sign.

‘You made the women before me believe they had no other choice. And to take money from you, sign their experiences away, sign what they went through away.

‘You get to go skip off and sing your little f***ing songs on stage like you’re a good dude.’
