So sad, but we guess it was her time to go.
Lulu, who thrilled New Yorkers by delivering the first baby gorilla ever born at the Central Park Zoo, died at her retirement habitat at in Ohio on Monday.
When Lulu's baby was born in 1972, the New York Daily News ran a naming contest that collected over 33,000 entries and selected Patty Cake as the winner.
The 46-year-old gorilla died after she began to suffer from seizures on Saturday.
Zoo officials say Lulu, known for her pink tongue that was perpetually sticking out, was a favorite among visitors.
Sounds like Lulu lived a long and happy life reaching a relatively old age for a gorilla.
Her daughter Patty Cake went on to produce 10 offspring of her own and now resides at the Bronx Zoo.
Rest in peace, Lulu!
