In many of her photosets she has appeared together with her steady picture-partner Adriana Malkova (also known as Denisa or Ariela).
In 1997 she appeared in three adult films under the alias of Katty Mass in explicit solo and girl-girl scenes, but otherwise she stands out as a glamour soft-core solo and girl-girl model with natural beauty. Hajkova together with her sister Gabriela Hajkova decided to stop modelling in May 2003, but from July 2005 she once again started accepting photoshoot offers when given very attractive payments.
