Jana Defi was first published on the web (as "Maria Swan") by the Polish erotic website Polish Busty in May 2005. Defi began nude modeling for the website in videos and pictorials. She modeled under different names, including Maria Swan and Princessa. Some of her most stunning photosets and videos have appeared on the high resolution glamour/artistic site MC Nudes, where's she's identified as "Princessa" and models without a stitch of clothing. She's done 10 photosets and 6 videos for MC-Nudes, beginning in 2005. She is also a glamour, lingerie and swimsuit model. Today, Jana Defi is one of the top Czech models and represented by the German agency, Markuslensch.
Because of Jana's enormous tits and slender figure, some have expressed suspicions that she's had breast implants (which is a big deal in the UK and cause for disqualification for becoming a Page 3 model). Pin Up Glam, where Jana is a model, responded to these accusations with convincing video testimony from a Los Angeles plastic surgeon and a radiologist. The video contained not only the testimony but a live, unedited sonogram exam of her breast tissue. Together, the video and the sonogram conclusively showed that no implants existed and that Jana's beautiful breasts are 100% natural. With the merge of Pin Up Glam and Pinup Files, however, the full video appears to have disappeared. Boobpedia has archived part of the movie which can be seen in the free movies section.
Defi achieved mainstream popularity in the UK, appearing with top UK glamour model Michelle Marsh on the front cover of the popular lads' mag Loaded in January 2007. She appeared on the cover of Loaded again in the March 2007 issue and was featured in the magazine's bonus 3D DVD. In the May 2007 issue she features as the magazine's top centrefold model. She has also appeared topless in the UK publications Zoo, Daily Sport and Nuts.
In January 2008 she successfully launched her own official website, called Janaglam. In July 2010 she closed it. As of July 18, 2010, the site is unavailable, and there is currently no determination as to if and when the site will return.
