Daniela Katzenberger's (36) mother Iris Klein (55) is in the hospital. As Klein's management confirmed to "RTL", the 55-year-old reality star ("I'm a star – get me out of here!") is in a clinic on Thursday evening. Further details on Klein's health are not known at this time. Jochen Österle, spokesman for the ADAC air rescue service, had previously confirmed to "RTL" that "a rescue helicopter was used on the street where Jenny Frankhauser lives".

According to the ADAC spokesman, an ambulance arrived at the scene by helicopter. However, the treating doctor then decided to accompany an unnamed patient in an ambulance to a clinic. Klein's prominent daughter Jenny Frankhauser (30), Daniela Katzenberger's half-sister, explained in an Instagram story on Thursday when a user asked how her mother was doing: "Not good at all. I don't want to say more about it [. ..]".

In the past few days, there had been rumors of an extramarital affair involving Klein's fourth husband, Peter Klein. Peter Klein is also known from various reality TV shows and formats. Together, the couple took part in the RTL show “Das Sommerhaus der Stars – Kampf der Promipaare” around 2020.
