Sydney Sweeney Tosses Lingerie at Stagecoach Festival!

cheekily threw underwear from her new Syrn lingerie line into the crowd at Stagecoach festival over the weekend.

The actress, 28, attended the star-studded event in where she surprised fans by appearing on stage during Diplo's set.

She wore a busty $269 corset from the brand - which she launched earlier this year - as she appeared before throwing garments from a bag into the crowd.

'Let's get some of these panties right here,' Diplo announced as he welcomed her, before telling revellers the underwear was for 'the ladies, not the guys'. 

She teamed the racy look with a lacy $49 Cowgirl Crush Frill Mini Skirt with tiered ruffles and added white cowboy boots.

The entrepreneur has been busy promoting her new underwear range, and the DJ/producer, 47, joined her at her SYRN saloon pop-up elsewhere at the festival.

A photo of Sweeney and Diplo was posted via the underwear brand's Instagram Stories on Saturday evening, with the caption, '@diplo Thanks for stopping by!!!' 

It comes amid news that the festival issued an emergency evacuation due to high winds over the weekend.

According to a report from Just Jared, festivalgoers on social media said there was an evacuation message announced over the speakers, displayed on stage screens, and on the corresponding livestream.

'Emergency Evacuation. The festival has been postponed until further notice. Please move quickly and calmly to the nearest exit,' attendees were directed in a statement typed over a red screen.

But less than an hour later, an updated message said, 'The show will resume. We are working to open doors and prep the site for your safety. Stay tuned for updates.'

The SYRN Saloon was stationed at the Citrus Courtyard near the Honky Tonk Bar and was open from '12pm to last call,' per Stagecoach's website.

A note on the site promised: 'We're bringing your favorite dive bar to the desert, reimagined the SYRN way.'

It also teased: 'Ice-cold SYRN cocktails, karaoke for the brave (or a few drinks in), classic dive bar games, and panty giveaways.'
