A bridesmaid told her best friend live on radio she was skipping parts of her wedding to attend a Taylor Swift concert. It didn't go well.

• A bridesmaid told her best friend she'll miss part of her wedding for a Taylor Swift concert.
• The revelation was made during a live radio broadcast, which saw the bridesmaid start to cry.

An Australian bridesmaid dropped a bombshell on her best friend, who is getting married in a little over three weeks, after telling her that she plans to skip part of the wedding to attend Taylor Swift's "Eras" Tour.

The revelation unfolded live on the radio, on The Fox's "Fifi, Fev, and Nick" show on Wednesday morning. As expected, it did not go over well.

Olivia, who didn't disclose her last name, fessed up during a segment about Swift's "Eras" tour disrupting plans.

The Swiftie said she had managed to secure coveted tickets to the Melbourne show on February 17 — the same night as the wedding of her best friend.

"I know how annoyed she's gonna be," Olivia told the hosts, according to a recording of the interaction.

The hosts then brought Jessie on air so that Olivia could own up to her double booking.

"I haven't told you that I got tickets for the Saturday, and this was done before Christmas," Olivia told her friend.

She said she hoped to find a "compromise."

Olivia proposed attending the wedding during the day, leaving a little early for the concert, and "hopefully" returning later in the night for the reception.

An unimpressed Jessie responded: "Is this a prank? Are you joking?"

Olivia said that she was serious, and added that she felt "really bad." But she defended herself by saying she'd been a Swiftie "for so long" and pointed out how hard it was to get the tickets.

Tickets for Swift's concerts sell out almost immediately, and resale tickets can go for astronomically high prices. In one instance, a Swift fan told BI that she paid $5,500 for resale tickets.

However, the bride-to-be seemed unconvinced by Olivia's explanation.

"You've known this since before December," she said. "It's three weeks before my wedding, and you're telling me now."

Jessie also poked holes in Olivia's plan, given the wedding's location in Yarra Valley, outside Melbourne.

"How are you going to come to my wedding and then go to Taylor Swift and come back? How is that even possible?" she said.

Exasperated, Jessie also mentioned that Olivia knew how annoyed she'd been with others who'd chosen to go to the Swift concert rather than her wedding.

Jessie added: "So you want to miss a part of my wedding to go to a Taylor Swift concert?"

Olivia later responded: "I know, I sound like such a bad friend."

As tensions escalated, host Fifi Box interrupted the call, saying it seemed to be getting personal.

Olivia began to cry, commenting on how "angry" her best friend appeared to be and how "anxious" she had been about telling her.

"I've been there through every step of the way, and when we were trying on the bridesmaid dresses, I was going to tell you," Olivia told Jessie.

But Jessie responded: "I don't even understand though, you've gone and bought tickets on my wedding date. I'm sorry, I'm not trying to be mean right now, I think I'm just angry before I'm even upset right now."

She added: "I want you there next to me on my day, and you're not gonna be there."

The hosts ended the segment there, while suggesting that they might look to ordering a helicopter to make the plan work.
