Over the weekend, Lainey Wilson delivered her first-ever headlining festival set after filling in for Luke Bryan at the 11th-annual Watershed Music and Camping Festival.

Bryan, unfortunately, had to pull out from his headlining slot due to illness, leaving Wilson to fill his shoes for the night. The female songstress closed out the three-day event as she took the stage on Sunday, August 6, and unleashed her signature Bell Bottom Country flare in front of approximately 22,000 fans. 

On Sunday afternoon (Aug. 6), Bryan took to social media to share the unfortunate news with fans.

"This is such a frustrating weekend.

'Shedders, I am sorry to let you down but I am not back singing – can hardly even talk still," Bryan shared. "This festival is one of the most beautiful places we perform and one of the most fun crowds always." 

"I know my friends on the show will bring a great time for you! Show them all what you got. Love ya, Luke!" Bryan's statement concluded.

The update came after the American Idol judge was advised by a doctor to cancel his Country On Tour date in Boise and suddenly postpone his concert at USANA Amphitheatre in Salt Lake City, Utah as well.

Even though Bryan couldn't make it to the Watershed stage, Wilson paid homage to the "Country On" singer by delivering several of his fan-favorites including "Drink a Beer," "Drunk on You," "Huntin', Fishin' and Lovin' Every Day," and "Country Girl."

In days following the event, Wilson took to Instagram to commemorate the milestone performance with a sentimental message inspired by words of wisdom from her father. 

"My deddy always told me to grab the reins and hold on tight when life gets crazy and that's just what we did Sunday night. @lukebryan we missed ya out there…get to feeling better❤️," she wrote before showing gratitude for all those who attended her set at the festival.

  "Thank you @watershedfestival for making my first headlining festival set one to remember.🤘🏻"

The rest of the weekend at The Gorge in George, WA featured a star-studded lineup of country artists including Cody Johnson, Keith Urban, Carly Pearce, Kameron Marlowe, and Parker McCollum, Conner Smith, Travis Denning, Avery Anna, Ernest and more. 

Luke Bryan is expected to continue on with his current Country On Tour on August 10 in Rogers, AR followed by a return to Nashville's Bridgestone Arena on August 12. In addition, the country superstar has been teasing a new song called "Southern and Slow" that he will be dropping this Friday.

Among all the fans' excitement, Bryan's mom, LeClaire also took to the comment section to share her anticipation for the catchy tune. 

"So excited for this. Love the train crossing. Beautiful," she wrote referring to the stunning image shared alongside a tease of the song. 

Later this year, Bryan will also embark on his annual Farm Tour and deliver show-stopping performances for the remainder of his Las Vegas residency.

As for Lainey Wilson, the "Heart Like A Truck" singer recently wrapped up her time on the road in support of Luke Combs' massive World Tour and now she is gearing up to join Eric Church for select dates of his The Outsiders Revival Tour.
