About
Sienna Day (born 7 May 1991, Darlington, County Durham, England) is a British adult-film performer and content creator who burst onto the scene in 2013 and quickly carved out a niche with her upbeat personality, trademark northern accent, and unmistakable platinum-blonde look. Standing around 5 ft 5 in (1.65 m), she has starred in hundreds of scenes for major studios such as Brazzers, Digital Playground, Evil Angel and Reality Kings, while also producing her own material for OnlyFans, Fansly and social media channels under the handle “adayinsienna.”
Her screen presence blends classic glamour with down-to-earth humour, a mix that helped her land guest spots on podcasts and mainstream interviews, including a long-form chat on the Modern Wisdom show where she broke down the business side of adult entertainment. More than a decade into her career, Sienna still films regularly, tours UK nightclubs as a feature dancer, and interacts daily with a loyal online fanbase.
Before Fame
Growing up in Darlington, Sienna kept busy with after-school jobs—first pulling pints in a local pub and later working double shifts as a waitress and kitchen assistant. An academically curious teenager, she enrolled at university to study Theology, hoping to become a teacher. But the cost-of-living grind and a desire for independence pushed her to explore alternative income streams. In 2013, inspired by friends already modelling for adult websites, she answered a casting call in London during her summer break. What started as a “just-one-shoot” experiment quickly snowballed: producers loved her confident energy, and within weeks she decided to pause her degree and pursue adult work full-time.
That leap involved tough conversations with family and close friends. In an early 2014 interview, she recalled phoning everyone who mattered to explain her choice before any scenes went online, so that “the news came from me, not a gossip site.” The upfront approach set the tone for a career built on transparency and self-management.
Trivia
- Award nods: Sienna earned back-to-back AVN nominations for Foreign Female Artist of the Year in 2016 and 2017, followed by an XBIZ nomination in 2018 for a three-way scene in Bulldogs.
- Podcast deep-dive: Her 70-minute Modern Wisdom appearance remains a fan favourite because she candidly discusses scene preparation, mental health on set, and strategies for “copyrighting your own body” in the subscription era.
- Fitness fanatic: Off-set, she boxes three mornings a week and credits weight training for sustaining the stamina needed for back-to-back shoot days.
- Viral cameo: A short clip of Sienna singing along to dance music while wearing a unicorn onesie went viral on TikTok in 2021, pulling thousands of new followers overnight.
- Geordie nightlife regular: Based near Newcastle since 2022, she is often spotted DJ-ing or pole-dancing at Friday promotional events, which led tabloids to call her “Tyneside’s most recognisable blonde.”
Family Life
Despite a very public career, Sienna draws a clear line around relatives. She has never revealed her parents’ names and rarely posts childhood photos, explaining that “they didn’t sign up for this gig.” Close family reportedly supported her decision once they understood she was in control of her image and finances.
Romantically, she keeps relationships low-profile—but headlines found her in June 2025 when Premier League defender Kieran Trippier was photographed leaving a Newcastle lounge with her shortly before announcing his separation from his wife. Sources said the two were simply enjoying a night out with mutual friends, yet the episode reminded Sienna how quickly gossip can flare when mainstream sport collides with adult fame.
At home, she shares a rescue dachshund named Luna, documents weekend hikes on Instagram Stories, and says her happiest non-work moments are “Sunday roasts with nan and endless gravy.”
Associated With
Throughout her filmography Sienna has teamed up with many of the industry’s most prolific co-stars, from British veteran Danny D to French performer Luke Hardy, and has appeared in multi-girl shoots with trans-Atlantic duo Rebecca More and Sophie Anderson—better known online as the Cock Destroyers—whose campy energy complements Sienna’s playful style. She is a studio favourite at Brazzers, having starred in signature series like Busty Brits, and is regularly booked by Naughty America for its UK–US crossover projects.
Away from studio sets, she collaborates with digital creators on OnlyFans bundle promotions and occasionally guest hosts live Q&A sessions for newer performers looking to navigate consent protocols and branding. Her appearance on the Modern Wisdom podcast introduced her to wellness podcaster Chris Williamson’s mainstream audience, broadening her reach beyond traditional adult circles.
With a decade of on-camera experience and a knack for reinventing her online persona, Sienna Day remains one of Britain’s most recognisable adult entertainers—balancing studio shoots, independent content, and a growing lifestyle brand, all while keeping her roots and personal boundaries firmly intact.
