Sydney Sweeney has unveiled a racy commercial for her lingerie brand Syrn, posing topless in a kitchen to promote her upcoming collection.
The 28-year-old Euphoria actress leaves almost nothing to the imagination in the advert, holding two small cakes over her chest before changing into a black lingerie set complete with a garter belt and stockings.
In subsequent scenes, Sweeney crawls on all fours across a dining table toward a large birthday cake. She tastes the frosting, suggestively licks it off her finger and thumb, and gazes into the camera alongside close-up shots of her cleavage and backside in various G-strings.

Sweeney is an American actress who achieved widespread recognition for her role as Cassie Howard in the HBO drama series Euphoria. She has since expanded into business as the founder of her own bodywear and lingerie line.

Birthday collection announcement
Sweeney, who turns 29 on September 12, explained that the racy campaign for her latest Syrn collection was specifically themed around her upcoming birthday.
Teasing the product release online, the star announced: "Celebrate my birthday month with my newest Syrn collection. Coming September 1st."

The wild advert drew a mixed reception in the comments section on social media. One fan asked if Sweeney was teasing a potential OnlyFans launch, while another commenter added, "I’ve seen more of Sydney than some women I've dated." A third user wrote, "Where can I buy the cake? Asking for a friend."

Lingerie brand background
Sweeney launched her lingerie brand earlier this year after the company had been in development since mid-2024. The brand achieved immediate popularity, selling out completely following its January launch.
Speaking to Cosmopolitan magazine in January, Sweeney explained her vision for the venture, stating: "I want to show women that we can take back our power and fully free ourselves."
Despite fitting a traditional Hollywood blonde bombshell archetype, Sweeney insists that Syrn is a diverse, female-first brand. Discussing her business model, she said: "My designers are all women, and I have an amazing diverse team. My models are a beautiful range of body types."

Fitness routine and training
To maintain her physical conditioning for modeling and acting, Sweeney stays in shape by taking regular classes at the boutique fitness studio Solidcore.
The studio describes its program as a "high-intensity, low-impact full-body workout on a Pilates-inspired reformer." Sweeney attends classes several times per week, telling Women's Health magazine that the routine makes her feel "toned and strong."

Upcoming acting projects
Outside of modeling and brand deals, Sweeney is adding another raunchy role to her acting portfolio. According to Deadline, the Immaculate star is set to star in a "retelling" of Sleepy Hollow.
The new take on the classic tale is based on author Lindsey Anderson Beer's debut novel Hollow, with Beer set to direct, produce, and adapt the project herself.
Deadline reported that "the story blends gothic atmosphere, psychological intrigue and erotic thriller elements into a contemporary, high-concept reinvention." The novel is a feminist reimagining of Washington Irving's 1820 short story The Legend of Sleepy Hollow.
Sweeney is expected to play the lead role of Van Tassel, who becomes involved in a seductive supernatural love triangle.
