Katerina Hartlova

Katerina Hartlova has built an unusually long and varied career. She started out as a glamour and nude model, then moved into hardcore at 19, and has worked steadily ever since. More than two decades later, she still performs her own solo, girl/girl, and boy/girl content, often alongside her real-life boyfriend.

Born in the small town of Chlumek in the Vysocina Region, Katerina is a Czech performer who has appeared in over 449 magazine covers, 239 photosets, and 210 videos for studios like Scoreland, Brazzers, and Karups. She also runs her own website, katerinaharlova, launched in May 2019. Her measurements are 41-25-37, with a natural 34G bra cup (UK 34FF, EU 75G) that expanded to a 34J after pregnancy. She has blonde hair, blue eyes, stands 5'6", and has an average build with a navel piercing.

One of the most distinctive parts of her career came in 2014, when she was pregnant and filmed a sex scene for Score with her boyfriend. After that, her breast size increased noticeably, and she produced a series of lactating scenes in solo, girl/girl, and boy/girl formats. She has also done bondage and bukkake work, including a pro-am scene for Spanish producer Torbe in July 2010 and another in July 2012. She identifies as bisexual. As of June 2026, her Instagram following sits at 4k. Her filmography includes work for Brazilian and Spanish producers, though she is best known for her long association with American companies.
