Jana Defi

Jana Defi is a former Czech adult and glamour model who worked in the industry from 2005 to 2010. She was born in Praha, Prague, Czech Republic, and is of Caucasian ethnicity. During her five active years, she appeared in 172 covers, 93 photosets, and 79 videos, achieving notable recognition in the UK market. She retired from modeling in July 2010.

Defi began her career in May 2005, appearing on the Polish website Polish Busty under the alias Maria Swan. She later gained wider fame as Princessa on the artistic site MC Nudes. In January 2007, she appeared on the front cover of the UK magazine Loaded alongside Michelle Marsh, and she repeated that achievement in March and May of the same year, also featuring in the magazine's 3D DVD. She also posed topless for publications like Zoo, Daily Sport, and Nuts.

A distinctive aspect of her career was the public verification of her natural breasts. After some questioned whether her breasts were natural, Pin Up Glam released a video featuring testimony from a plastic surgeon and a radiologist, along with a sonogram exam, confirming that her breasts were 100% natural. Following her retirement, she chose to undergo breast reduction surgery, which marked a departure from her former image. She speaks seven languages, including Czech, English, German, and Polish.
