Niall Horan and Thomas Rhett had to delay their co-headlining concert in Pennsylvania by 24 hours due to "severe weather".

The former One Direction star and the country singer had been due to perform at the Hersheypark Stadium on Saturday (18.07.26) but were "forced into a corner" and advised not to do the show because of storms in the region, so they will now take to the stage on Sunday (19.07.26) instead.

Niall shared in a video on Instagram: "We've been, kind of, sat with our teams and the promoters and the meteorologists all morning.

"It feels like there's a lot of severe weather in the area and some bad weather conditions and thunderstorms threatening the show. So, we have been, kind of, forced into a corner and we will have to reschedule."

Niall insisted he and Thomas hadn't wanted to postpone the show but felt it was important, and advised fans they could get their money back if they couldn't make the rearranged day.

He added: "[It's] something we didn't want to do, but we do want to stay in town and a show for you guys. If you have a ticket, you can come tomorrow. If you can't make the show tomorrow night, you will get a full refund for your ticket.

"We're obviously said to have to do this, but this is what we're gonna have to do."

Meanwhile, Thomas, 36, noted the well-being of fans was the most important thing.

He added: "We love y'all, and y'all's safety is first and foremost our biggest concern. We want to give y'all the show that we have prepared. We just couldn't guarantee that for tonight.

"So, it's a miracle that the venue's available tomorrow, that me and Niall are both here tomorrow and so we'll see you guys tomorrow night, ready to freaking rock. We love y'all so much."

The two singers previously co-headlined a show in Nashville earlier this month, where they each performed their biggest hits before teaming up on their Old Tricks duet.

Thomas wrote on social media afterwards: "What in the world. Nashville, I had the time of my life with y'all! Should we do it again @niallhoran?"
