Sydney Sweeney, the star of "Euphoria," has brought the wild west to the Stagecoach Country Music Festival! The 28-year-old actress made a surprise appearance on Diplo's annual HonkeyTonk set on Saturday, April 25, where she unleashed a whirlwind of lingerie on an audience of wide-eyed festivalgoers.

Sweeney donned a baby blue minidress and knee-high cowgirl boots, accessorizing with a delicate necklace featuring an "SB" charm, a nod to her boyfriend, Scooter Braun. She paired her outfit with a fierce energy on stage, as she slung panties from her new lingerie line, SYRN, which launched earlier this year.
Diplo welcomed Sweeney to the stage, urging the crowd to get some of her panties. He clarified that they were for "the ladies, not the guys," as Sweeney launched her undergarments into the crowd from a plastic bag. She was all smiles as she waved and blew kisses to the eager festivalgoers.
The sexy stage scene wasn't the only place Sweeney left her mark over the weekend. She also hosted a pop-up event at her SYRN Saloon, a karaoke bar where she even grabbed the mic for a duet of "Choosin' Texas" by Ella Langley with Bailey Zimmermann. The fun was documented on SYRN's official Instagram account with a slideshow of videos and photos of Sweeney at Stagecoach.
Sweeney's trend of making headlines in promotion of SYRN continued, despite backlash after a video obtained by TMZ showed her decorating the Hollywood Sign in bras for her lingerie brand. However, that didn't stop the Emmy-nominated star from moving forward with her business plans.
