Sienna Day

I've known her for ages, I think since 2020. British, funny, amazing. I've filmed a lot of scenes with her, and we've met up in Ibiza, Barcelona, London and plenty of other places. A really cool girl.

Sienna Day is an English glamour model and adult film actress, born in May 1991 in Darlington, County Durham. She is a blonde with blue eyes who began in softcore glamour modelling and became one of the best-known British performers of the 2010s.

She started in 2012–2013, at 21–22, with British glamour and tease work for Only Tease, Pix and Video and Joy Bear. She soon moved into hardcore and international productions for Naughty America, Big Tits at School, Brazzers, MYLF, Private, Porn World, Immoral Live, GF Revenge, Blacks on Blondes and Hands on Hardcore. Babepedia lists more than 370 videos and over 500 covers.

Her international work earned her AVN nominations for Female Foreign Performer of the Year in 2016 and 2017. She was also nominated at the 2018 XBIZ Awards for Best Scene – Feature Release (Bulldogs) and at the 2019 XBIZ Europa Awards for Best Sex Scene – Gonzo (Game).

She remains active more than a decade into her career.

Before joining the industry Day was studying philosophy and religious studies at university. She told XBIZ in 2025 that she did not want to become a teacher, was "always quite promiscuous", and that an ex-boyfriend suggested she look into porn. "I was just 22, a little bit adventurous, a little bit wild," she said. She thought at first she might do it for two years, then five; twelve years in, she said, "I'm dying on this hill." She misses the early studio days, when performers met more people on set, and says self-producing is harder work because of the content planning, sales, marketing and editing involved. In 2025 she won the fan-voted MILF Creator of the Year award at the European XMA Awards in Amsterdam, joking that at 34, with no children, the label simply comes with being over 25 with implants: "Johnny Sins isn't a plumber. You're just playing a role." She lives in the north of England, practises pole dancing at an advanced level and has a Weimaraner.

In 2019 she was a guest on Chris Williamson's podcast Modern Wisdom, where she talked about how performers get started, what happens on set, preparing for anal scenes, how to make a career last longer, and how to turn studio features for companies such as Brazzers and Fake Taxi into a following for her own membership site.

On James English's Anything Goes podcast in 2023, she said she had been studying at Leeds Trinity, a Catholic university, when she decided to "monetise" her high sex drive. She flew to Los Angeles to shoot her first scene in 2013 and FaceTimed her mother to tell her what she was doing. That openness mattered: soon afterwards her mother received an anonymous blackmail-style letter with a photo from one of her scenes, saying "look at your little angel now". "I was mortified," she said. "Who does that?" The blackmailer never got any money. By then she had made about 85 films. In 2016 a Metro features writer visited her on the Kent set of Joybear's storyline film The Invitation. He described her as "an incredibly friendly Northern lass with a gentle Geordie accent" and noted the slow, carefully planned shoot behind the company's "posh erotica".
