Sydney Sweeney goes topless with her finger in her mouth in her most provocative lingerie ad yet

Sydney Sweeney has stripped down for the boldest and most revealing advertising campaign yet for her lingerie brand, Syrn.

The 28-year-old Euphoria star leaves little to the imagination in a new promotional video. In the clip, the actress, dressed only in lingerie, first busily “works her magic” over a batch of pastries in the kitchen before stripping down further, covering her breasts with just two tiny cakes.

In the next scene, Sweeney slips into a black lingerie set complete with a garter belt and stockings, before crawling on all fours across the dining table toward a large celebration cake.

Looking seductively into the camera, she tastes the frosting and teasingly licks her finger. The video is also packed with eye-catching and provocative shots, including close-ups of her cleavage and backside in various thong styles.

The star of The Housemaid, who turns 29 on September 12, revealed that the racy campaign was created specifically to coincide with her upcoming birthday.

“Celebrate my birthday month with my new Syrn collection. Available September 1,” the actress teased.

The sizzling video sparked a flurry of mixed reactions in the comments. One fan jokingly asked whether Sweeney was hinting at launching an OnlyFans account, while another quipped: “I’ve seen Sydney without clothes more than some of the girls I’ve dated.”
