Let Syd eat cake.

Sydney Sweeney is gearing up for her 29th birthday, starting the celebrations early with some lingerie-clad photos, naturally.

“Celebrate my birthday month with my newest @syrn collection 🎂,” she wrote on Instagram, teasing her Syrn lingerie brand’s forthcoming “Birthday Boobs” collection.

In the video, she models teddies, lace push up bras, garters and more while climbing along a long dining table with human-sized cake she could practically climb inside.

In the pics, she has her cake and eats it too, laying on a table while licking the dessert of her fingers.

More campaign images depict Sweeney modeling sets in a 1970s-era kitchen, using milk bottles, rolling pins and balloons as her props as she decorates a heart-shaped cake

The latest drop launches on September 1, slightly less than two weeks before her actual birthday and was “inspired by Sydney’s own personal take on romance,” per a press release from the brand.

There are hand-drawn forget-me-not florals, bows and embroidery, including the words “I really love you” woven into the designs in Sweeney’s handwriting, plus colorways including the “Euphoria” actress’ favorite baby blue. Prices range from $19–$64, sizing XXS–3X and 44 bra sizes.

Sweeney launched the lingerie company back in January, modeling the collections on a small-drop basis with capsule collections launching every few months.

She teased her birthday campaign earlier this month, sharing behind-the-scenes polaroids on her Instagram account.

The only question left is, what will Syd wear for her big day next month?
