Sydney Sweeney is ramping up promo for her newly dropped Birthday Boobs collection as her SYRN lingerie brand releases a special line for her 29th birthday. The actress updated her Instagram this week with photos and videos showing a birthday-themed shoot, following her hot-and-heavy birthday cake footage shared last week. Sydney, who made headlines five days ago for grabbing eggs from her fridge while stripped to undies, prepared her birthday cake in lingerie to introduce Birthday Boobs, and she was back for more on Tuesday morning. Showing off her killer curves in her 2026-launched lingerie brand, the Hollywood star shouted out the “early access” she was treating fans to, and comments came in fast.

The slide-heavy gallery, which also included Sydney crouching down by her fridge and holding some fresh milk, peeked the star’s thong-clad rear in some images, with the final slide including a collage of video moments from her shoot. In a caption urging fans to shop Birthday Boobs, Sydney wrote:” Early access to @syrn birthday boobs collection available now.” Birthday Boobs is released today, September 1. Sydney will turn 29 on September 12.
