Sydney Sweeney turns up the heat ahead of 29th birthday in new lingerie campaign

Sydney Sweeney is starting her birthday celebration early.

The "Euphoria" star posed in a new retro-inspired campaign for her lingerie brand, SYRN, weeks before she turns 29 on Sept. 12.

In the newly released photos, Sweeney models a powder-blue floral lingerie set inside a vintage-style kitchen. One image shows the actress posing beside a refrigerator, while another captures her crouched in front of the open appliance holding a glass bottle of milk.
