Jana Defi, born January 10, 1984, in Prague, Czechoslovakia, is a Czech glamour and adult model, also known as Maria Swan or Princessa.

Jana kicked off her modeling career in 2005 as “Maria Swan” on Polish Busty, later appearing as “Princessa” on MC Nudes.

Known for her natural, eye-catching figure, she faced breast implant rumors, debunked by a Pin Up Glam video with a sonogram proving her breasts were 100% natural.

She gained UK fame, gracing Loaded’s cover with Michelle Marsh in January 2007, and appeared in Zoo, Daily Sport, and Nuts. Jana retired in July 2010 after five years, shutting down her site Janaglam. Post-retirement, she underwent breast reduction surgery and has since kept a low profile. Fluent in seven languages, including Czech, English, German, and Polish, she leveraged her skills in her global modeling career.
