Crystal Klein has the rare distinction of being both a Playboy Playmate, under the name Christiane Vogt in the October 2004 Croatian edition, and a Penthouse Pet of the Month for March 2005. She’s originally from Vienna but now works in the America porn industry. She began that career trajectory as a swimsuit model in Maui, which led to Los Angeles and adult work. Crystal has played piano while nude on The Howard Stern Show and simply got nude in A Secret Revealed (2007) and The Passion of Fashion (2007).
