Updated July 29, 2025 at 2:18 PM AKDT Sydney Sweeney's "great jeans" are causing quite a stir — and it's not because of the quality of the denim. Clothing retailer American Eagle's latest ad campaign centers around the 27-year-old star, known for roles in Euphoria, Anyone But You and Once Upon a Time in Hollywood. The campaign's tagline —"Sydney Sweeney has great jeans" — plays on the word "genes" which naturally leads viewers to think about the genetics of the blonde-haired, blue-eyed woman. "Genes are passed down from parents to offspring, often determining traits like hair color, personality and even eye color. My genes are blue," Sweeney says in one video. The campaign has sparked backlash online. Some social media users have accused American Eagle of teasing at eugenics, a discredited scientific theory popular among white supremacists that the human race could be improved by breeding out less desirable traits.
