Headliner Lainey Wilson goes undercover at Stagecoach to interview fans and 'they have no clue'

Country music star Lainey Wilson has gone undercover at Stagecoach Music Festival, giving fans the surprise of their lives.

Two days after the Grammy-winning artist headlined the festival on Saturday, Wilson, 33, revealed in a TikTok video that she headed into the crowd with a clever disguise.

See the video above. 

"It's Britney bitch," Wilson announces in the video, mimicking Britney Spears' iconic line, wearing a black bob wig. 

The star documented her transformation into alter-ego Britney West "from Temecula" as she ditched her Louisiana twang for a California girl accent.

With her wig, cowgirl hat, sunnies and costume on, Wilson walked into an estimated 80,000 person crowd to interact with fans.

"They have absolutely NO CLUE," the Somewhere Over Laredo singer grinned.

As she interviewed unsuspecting festivalgoers, one young girl revealed she was most excited to see Lainey Wilson perform.

Wilson gasped and the young girl still had no idea she was being interviewed by the star.

"Do you happen to have a favourite Lainey Wilson song?" the disguised star then asked a group of fans.

Staying in character, Wilson responded to cameras, "I'm not sure about that Lainey Wilson girl" before revealing her true identity.

"Just so you know ... I am Lainey Wilson," the singer revealed to her fans before they screamed in disbelief.

"Not it's not, oh my gosh!" one reacted.

"Britney West comin' atcha from the streets of Stagecoach ?," the star captioned the original video.

Wilson's headline performance was delayed on Saturday after a night of wild winds swept through the Stagecoach festival grounds.

An estimated 80,000 festivalgoers were temporarily evacuated after wind gusts reached up to 105 kilometres per hour.

Despite the delay and set cancellations, the show was back on the road in just a few short hours.

Wilson took to the stage for a triumphant performance less than two hours after the initial chaos, thanking crowds for toughing out the wild weather to be there.

"Thank you so much for sticking out the wind," the singer told the crowd, per Billboard.

"Hopefully you sat in y'all's cars for a bit and drank some tequila."
