Barabara Kelly has passed away at the age of 45.
Her family announced this on Facebook.
The German-British singer was part of the musical family The Kelly Family for many years.
“Our beloved sister Barby passed away after a short illness,” the Kelly Family's Facebook profile wrote.
It is not known what Kelly died of.
The family says they are deeply sad and hopes that the press respects that they want to be left alone in the coming period.
Barbara Kelly is said to have died on April 15.
Barbara Kelly has lived in isolation for the past twenty years because she is said to have had psychological problems.
In recent months, however, she has shown herself to be ready to attract the attention of fans and the media.
The Kelly Family was formed in 1979 and has consisted of members of the Kelly family ever since.
In the 1990s, the family enjoyed tremendous success across Europe.
After the turn of the century the band faded into the background, but a return in 2017 and 2018 drew large audiences to large concert halls.
