Her breakthrough came in the same year when she featured in the VOX television soap opera Auf und davon – Mein Auslandstagebuch ("Up and Away – My Diary Abroad").

In the show, a camera crew followed Katzenberger as she attempted to break into photographic modelling in the United States, including trying to meet Hugh Hefner and applying to appear in the American Playboy magazine, neither of which succeed.

In the second season of the show, the viewers follow her as she undergoes plastic surgery to further her glamour modelling career.

Katzenberger signed a recording contract with EMI in May 2010, and her first single, a cover of Samantha Fox's "Nothing's gonna stop me now" was released.

She has signed numerous advertising deals with companies such as Kaufland, Lidl, Poco,[7] and Uncle Sam.
