Sydney Sweeney Goes Topless with Birthday Cakes for Sexy Lingerie Promo

Sydney Sweeney is kicking off her birthday month in unforgettable style. The *Euphoria* alum posted a sizzling new video to Instagram on Thursday, August 26, showing off her latest collection for her Syrn brand ahead of her upcoming September birthday. The 28-year-old star stunned fans by ditching her top and posing with baked goods for the sexy new promotional spot. The clip opens with Sweeney in a retro kitchen setting, reaching into a refrigerator while dressed in a sheer pastel blue floral bra and matching G-string. She accessorized the look with coordinating garters and thigh-high stockings. After pulling out a bowl of eggs, she turned away from the lens, giving viewers a quick glance at her backside before moving on to her next look. ## What happens in Sydney Sweeney's new Syrn video? Next up in the video, Sweeney got busy prepping her birthday treats. Dressed in a pastel pink halter top featuring a floral bra underneath, she measured flour and mixed up ingredients at the counter. In one cheeky moment during the baking process, she brushed excess flour directly off her butt before stepping away from the kitchen workspace. The main highlight of the campaign arrived when the actress decided to leave her bra behind entirely. Going completely topless, Sweeney strutted across the room holding two frosted birthday cakes strategically over her chest. She wore high-cut pink underwear with ruffled lace straps for the moment, walking over to place both cakes down onto a dining table. ## How is Sydney Sweeney marking her birthday month? For the grand finish of the promo, Sweeney swapped into a black sheer bra paired with cheeky string underwear and black stiletto heels. The star crawled straight across the dining room table toward yet another cake, closing out the video clip with plenty of tabloid-worthy energy. The bold campaign serves as a double celebration for the star, highlighting both her brand's newest intimate apparel line and her entry into her birthday month. With September right around the corner, Sweeney proved she knows exactly how to make a show-stopping entrance into her 29th year.
