Sydney Sweeney is marking her upcoming 29th birthday with a new campaign for her lingerie brand, Syrn. The "Euphoria" actress shared images and a video from the "Birthday Boobs" collection shoot, which features romantic designs and a playful, cake-filled aesthetic. The latest Syrn drop is slated to launch on September 1, just before Sweeney's birthday later that month.

The campaign images depict Sweeney modeling lingerie sets in vintage-inspired settings, utilizing props such as balloons, milk bottles, and cakes. One video shows her interacting with a large cake as part of the celebratory theme. In other photos, she is seen on a table adorned with cakes and balloons.

The "Birthday Boobs" collection is described as inspired by Sweeney's personal take on romance, incorporating elements like hand-drawn forget-me-not florals, bows, and embroidery. Some designs feature phrases like "I really love you" woven in Sweeney's handwriting. The collection's color palette includes baby blue, which is noted as the actress's favorite shade. Prices for the collection range from $19 to $64, with sizes available from XXS to 3X, including a wide range of bra sizes.

Sweeney launched Syrn in January, with the brand releasing capsule collections on a small-drop basis. She had previously teased the birthday campaign with behind-the-scenes Polaroids shared on her social media accounts.
