News.com.au suggests Pink's remark about "children being children" was likely in reference to the words of New York architect Peter Eiseman who helped design the Berlin memorial.
In an interview with the BBC in 2017, Mr Eisenman said: "People have been jumping around on those pillars forever. They've been sunbathing, they've been having lunch there, and I think that's fine. It's like a Catholic Church, it's a meeting place, children run around, they sell trinkets.
"A memorial is an everyday occurrence, it is not a sacred ground."
Pink received a slew of supportive feedback from fans and fellow celebrities, with American actress Selma Blair commenting: "I love Berlin too. I love that what happened is not being forgotten. I love this celebration of life. I love you."
One woman wrote: "When i was little my parents took me to ‘Westerbork’, a museum that used to be a horrible place during wwII. I was running and singing around and my mother tried to stop me... until an old man said: Please let her joy fill this place. I survived this place, please let your daughter celebrate her freedom this way. I never forgot... ❤️"
