Summertime is for hanging with your friends, and what better way to enjoy the season than to gather 60,000 of them for a two-night stadium blowout? Old pals Niall Horan and Thomas Rhett announced a pair of such hangs on Tuesday morning (March 10) when they rolled out the dates for a two-night-only stadium stand this summer.

The Live Nation-promoted gigs will take place on July 9 at GEODIS Park in Nashville, Tenn., followed by a show at Hersheypark Stadium in Hershey, Pa. on July 18. The concerts will be the first time the pair have performed stadium headline shows together as well as the first-ever headline concerts at GEODIS Park for both men; Kashus Culpepper and Emily Ann Roberts will open both shows.

Tickets for Thomas Rhett & Niall Horan Live will go on sale beginning at 10 a.m. local time on Wednesday (March 11) through both artist’s fan clubs. Additional pre-sales will run throughout the week ahead of the general on-sale, which begins on Friday (March 13) at 10 a.m. local time; click here for general on-sale ticket information.

“Niall and I have been buddies for nearly a decade now, but one thing we’ve not done yet is officially tour together,” said Rhett in a statement. “There’s nothing I love more than being on the road alongside longtime friends — it’s going to be a blast for us and the fans.”

Horan added, “When TR brought up the idea of doing these, I immediately got so excited just thinking about it. We’ve been friends for ages and it just makes perfect sense.”

In October, Horan teamed up with his longtime friend Rhett on a re-worked version of the country singer’s “Old Tricks” from the deluxe version of his About a Woman album. At the time, Rhett said in a statement, “Niall and I have been buddies for six or seven years now — anytime I’m over in the U.K. or he’s in Nashville, we always try to link up. We’d talked about doing something together for a long time, but I never imagined it would be this song.”

Horan is gearing up to release his as-yet-untitled fourth solo studio album, with he LP’s emotional new single, “Dinner Party,” due out on March 20. Before hitting the road with Horan, Rhett will open a run of three stadium shows on Morgan Wallen’s Still the Problem tour beginning on April 10.
