Sydney Sweeney is bringing the wild to the west!
The Euphoria star, 28, made a surprise appearance at the Stagecoach Country Music Festival over the weekend when she joined Diplo on stage at his annual HonkeyTonk set for a lively musical moment turned underwear whirlwind on Saturday, April 25.
Sweeney slung panties from her new lingerie line, SYRN, which launched earlier this year in January, into a sea of wide-eyed festival goers who swarmed Diplo's desert stage as the electric beats by the chart-topping DJ bumped in the background.

Dressed for the west, Sweeney paired white, knee-high cowgirl boots with a baby blue minidress. Its plunging neckline was adorned with white, lace ruffles that put her necklace on full display — a dainty piece of jewelry with an "SB" charm, seemingly a nod to her boyfriend, Scooter Braun.
Sweeney's PDA move comes shortly after she and Braun, 44, made their coupling Instagram official on April 15. The music producer reshared a photo of the two cozying up at what appeared to be the Euphoria season 3 premiere to his Instagram Stories.
He captioned the post, "lucky bastard."

As seen in videos on social media, Sweeney is all smiles as she launches her undergarments, plucked out of a plastic bag and into the crowd. She then waves to the eager festival goers, and at one point, blows a kiss to those in attendance as Diplo hypes her up on the mic.
“Let’s get some of these panties right here,” Diplo announced as he welcomed Sweeney, before clarifying that the pieces she was giving away were meant for "the ladies, not the guys," reported Harper's Bazaar.

The sexy stage scene wasn't the only place Sweeney left her mark over the weekend. She continued the fun at her SYRN Saloon, hosting a pop-up event at a karaoke bar (she even grabbed the mic for a duet of "Choosin’ Texas" by Ella Langley with Bailey Zimmermann).
The fun was documented on the official SYRN Instagram after the weekend.
"Scenes from day 1 at the SYRN Saloon ⭐️🐎," read the caption alongside a slideshow of videos and photos of Sweeney at Stagecoach.

The underwear slinging follows Sweeney's trend of making headlines in promotion of SYRN. Prior to its launch, the White Lotus star drew backlash after a video obtained and published by TMZ on Jan. 26 showed her decorating the Hollywood Sign in bras for her lingerie brand.
A statement given to PEOPLE by the Hollywood Chamber of Commerce (who owns the intellectual property rights to the image of the landmark) revealed that she was "not authorized" to do so.
However, that didn't stop the Emmy-nominated star from moving forward with her business plans.
