Sydney Sweeney made a high-profile appearance at the Stagecoach Music Festival in Indio, California, earlier this week to host a special event for her lingerie brand, Syrn.

On Thursday, the 28-year-old actress shared a series of images and videos on Instagram documenting the festivities at the “Syrn Saloon.”

The event featured a star-studded karaoke lineup, with Sweeney taking the stage to perform alongside major artists including Dan + Shay, Diplo, Lance Bass, Shaboozey, and Riley Green.

Adding to the evening's highlights, Sweeney was joined on stage by her boyfriend, Scooter Braun, to perform a rendition of Toby Keith’s classic, "I Shoulda Been a Cowboy."

Throughout the three-day festival, the actress showcased several looks from her collection, including a sleeveless brown corset paired with denim shorts and cowboy boots, as well as a baby-blue corset with a lace skirt.

The venue itself was intricately decorated with items from the Syrn line and custom currency featuring the star's likeness.

The festival appearance comes amidst significant buzz surrounding the third season of the hit HBO series Euphoria, which premiered earlier this month.

Sweeney’s character, Cassie, has sparked intense online discussion following a five-year time jump that sees her exploring a career as an OnlyFans model.

While some viewers have criticised the provocative nature of the storyline, the actress recently celebrated the show's continued commercial success, noting that the premiere surpassed 20 million worldwide viewers. New episodes of the series continue to air weekly on Sundays.
