Promi Big Brother 1 is the first season of Promi Big Brother, the German equivalent of Celebrity Big Brother. Similar to other Celebrity Big Brother series, Promi Big Brother followed 13 celebrities ("promis") as they lived together in a house for 15 days. This series contained a notably diverse cast of celebrities from around the globe.
American actor David Hasselhoff, who had gained a large following in Germany through his roles, took part in the show, but left the house on Day 5 due to a family issue.
German actress Jenny Elvers was crowned winner of this season on Day 15.
New Promi: As a result of David walking from the house, British reality star Georgina Fleur moved into the house on Day 7.
Fake Eviction: On Day 8, Natalia was fake evicted by Big Brother and lived in a Secret Loft for 24 hours. This granted her immunity from the Day 8 nominations.
Special Guest Star: On Day 12, American actress Pamela Anderson entered the house as a special guest and stayed in the house until the final day.
Pamela was also granted the ability to save one of the four housemates nominated on Day 12 from nomination. She chose to save Manuel.
