Sydney Sweeney is kicking off her birthday month with a bang — and very little else. The Euphoria star, who turns 29, has rolled out a cheeky new campaign for her luxury lingerie brand SYRN, and the internet is reacting accordingly.
In a video shared Thursday on Instagram, Sweeney models several pieces from her upcoming “Birthday Boobs” collection, which drops September 1. The clip features the actress in fancy pink panties with her hair tumbling in loose curls — and at one fleeting moment, she goes topless, using birthday cakes to cover her chest.
“Celebrate my birthday month with my newest @syrn collection coming September 1st,” she captioned the post, flagging the brand’s forthcoming drop.
The video was also shared on X, where it racked up nearly nine million views in less than 24 hours. The comments section flooded with more than a thousand reactions, including one user who declared: “Fuck me. She is gonna be bigger than Victoria Secret.”
Sweeney launched SYRN back in January, modeling the collections in small drops over the following months, as Breitbart News previously reported. The actress has been anything but subtle in promoting the brand — she famously filmed herself hanging bras on the Hollywood sign, a stunt the city reportedly did not approve.
For the birthday collection, Sweeney leaned into a romantic aesthetic that feels personal to her. “I’m a lovergirl at heart, so of course I wanted my birthday collection to be Romantic. It felt like the perfect excuse to make something really feminine and special,” she said in a press release.
She teased the campaign earlier this month, sharing behind-the-scenes Polaroids on her Instagram account, building anticipation before the full reveal.
The ‘Birthday Boobs’ Collection
The collection itself is described as a range of intimate apparel that highlights Sweeney’s famous figure. The campaign video, with its playful cake-eating theme, is designed to feel celebratory and indulgent — a fitting tone for a birthday drop.
Fans have responded enthusiastically to the risque aesthetic, with the X post generating viral momentum that shows no signs of slowing. Whether SYRN will indeed rival Victoria’s Secret remains to be seen, but Sweeney’s ability to command attention is clearly not in question.
The “Birthday Boobs” collection officially launches September 1, just in time for the actress’s birthday celebrations. For now, fans can enjoy the preview — and the internet’s reaction to it.
