Kelly Trump originally trained as a dental assistant, then began dancing professionally. In 1994 she was asked by a friend whether she wanted to participate in nude modeling and adult films. She soon received an offer to perform in a film being shot in the Caribbean. Only after the casting sessions did she discover that the movie, Dangerous Dreams, was a pornographic movie. She decided to follow through with her decision and thus began her career in the adult film industry.
Notable porn actresses she acted with include Timea Vagvoelgyi, Regina McDavis, Selen and Ursula Moore
She has performed in story-driven German adult films, such as German Beauty (an adult adaptation of American Beauty), Eiskalte Engel (Ice-Cold Angels), the 00Sex series (based on James Bond and Ariella the Mermaid. She has also acted in a small number of American adult films, including films for Wicked Pictures.
In 1999, she starred as the title role in "Supergirl: Titten aus Stahl" ("Supergirl: Tits of Steel"), an underground favorite amongst comic book fans. Kelly Trump also has the distinction of being the only other actress, aside from Helen Slater, to portray Supergirl in a live action film.
Trump announced her retirement from the adult film world at the 2001 Venus Awards in Berlin in order to pursue a career in mainstream TV and film.
One unusual career move was her involvement in RTL Promiboxen, German TV's version of celebrity boxing. For the 2003 program, she trained as a potential substitute in case the announced boxers, Tanja Szewczenko and Samantha Fox, were unable to participate in their bout.
For the 2004 program, Trump was announced as one of the celebrity boxers, with her opponent being Juliane Ziegler, the 22-year-old star of German TV reality program der Bachelor. Trump underwent four weeks of intensive training with noted martial arts trainer Klaus Waschkewitz. Trump's ring name was "Bad Babe" while Ziegler's was "Red Rose".
On May 1, 2004, Trump stepped into the boxing ring before 1800 spectators at Cologne’s Colleseum, but was soundly beaten by Ziegler who easily out-reached and out-pointed Trump to win the three-round bout by a unanimous decision.
Since January 6, 2005, she is the host of the German television show, Love Check.
