She's up there slapping cops in heaven now.

Zsa Zsa Gabor, the Hungarian beauty who some called the OG Kim Kardashian, is dead just shy of 100 years old ... TMZ has learned.

We've learned Gabor died Sunday after suffering a heart attack. She was rushed to the hospital where she was pronounced dead.

Her husband Frederic Prinz Von Anhalt held birthday parties for Gabor the last few years, but she was so sick visitors were not allowed in her bedroom.

Zsa Zsa and her younger sister Eva were socialites in Beverly Hills for decades. Zsa Zsa had nearly 80 tv and film acting credits, but most often she played herself. She was married to Conrad Hilton, Paris's grandfather, from 1942-1947.
