In 2004's "Der Clown", she co-stars with Eva Habermann, the original Zev of season one of Lexx, who had to relinquish her role after the first year of the series due to scheduling conflicts. As a play on her first name, the name of Xenia's character was changed to Xev.
She is a former lingerie model. Xenia also worked as a model and got endorsements for Triumph Lingerie, Douglas Perfume Store in Europe, and Manhattan Cosmetics.
Xenia: (on doing Xev in "Lexx") At first, I wasn't so sure if I really wanted to take that character. I thought, what is the point of playing the sex kitten on a show? That may be nice for maybe an episode, but not for an ongoing series. But I soon discovered that I pretty much had the freedom to help develop the character and take her wherever I wanted to...
Xenia: (comparing herself to her character in "Lexx") I probably have a strange kind of humour in real life too, but I guess that's pretty much the only thing we have in common. Everything else is fake. Even the hair colour's fake!
Xenia: I was told by my grandmother's cousin who was an actress in the '20s – she was 86 and I was 4 at the time – that I would be an actress one day.
