Sydney Sweeney stunned fans after posting a behind-the-scenes video promoting her lingerie brand in which she briefly lifted her T-shirt to reveal a bra from her own collection.
The actress shared the clip while filming promotional content for Syrn, the lingerie line she launched last month with a focus on size inclusivity and bold marketing.
In the video, Sweeney stands in the back of a pickup truck wearing a white T-shirt and denim shorts while walking viewers through several pieces from the brand’s Valentine’s collection.
After explaining the products, Sweeney unexpectedly pulled up her shirt and revealed a nude lace bra, catching both fans and her crew off guard.
Laughter erupted behind the camera as the actress smiled and acknowledged what she was wearing.
“And I’m wearing, from the first collection, Seductress lightly lined plunge,” Sweeney said, before lowering her shirt back down.
She ended the clip by telling fans she hoped they would love the collection, which she described as designed to be both sexy and empowering.
Sweeney, 28, has made herself the face of the brand, frequently modeling the pieces and appearing directly in marketing content.
Syrn was created with extended sizing in mind, offering options for busts up to 42DDD, a detail Sweeney has repeatedly emphasized.
The actress has said her personal experiences influenced the brand, including developing a 32DD figure at a young age and struggling to find well-fitting lingerie.
The promotional strategy has leaned heavily into Sweeney’s star power and viral appeal, with clips quickly spreading across social media.
The brand’s initial launch campaign featured Sweeney in multiple lace sets and was widely described as provocative.
Syrn has also drawn attention due to its high-profile backing, per news.com.au.
Amazon founder Jeff Bezos and his wife Lauren Sanchez are reported to be supporting the venture after Sweeney attended their wedding in Venice last year.
Those involved with the brand have compared its ambitions to major celebrity success stories in the lingerie market.
Kim Kardashian’s Skims brand, launched in 2019, is now valued at roughly $5 billion.
Rihanna’s Savage x Fenty brand has also surpassed $1 billion in valuation.
Industry observers say Sweeney is positioning Syrn to compete in the same lucrative space by combining celebrity visibility with direct consumer marketing.
A source previously told The Sun that Sweeney’s popularity has made her one of the most talked-about women in Hollywood.
The source added that those close to the business believe Syrn could eventually earn her more money than acting.
Sweeney has continued to promote the brand aggressively through social media rather than traditional advertising.
The latest video reinforced that strategy, blurring the line between casual content and commercial promotion.
Fans reacted quickly, with many praising her confidence while others noted the shock value of the reveal.
The clip succeeded in drawing attention to Syrn ahead of Valentine’s Day, a key sales window for lingerie brands.
Sweeney has not commented further beyond encouraging fans to support the collection.
For now, the actress appears fully committed to building Syrn alongside her acting career.
