Lauren Bacall, the tough-talking femme fatale who taught Humphrey Bogart how to whistle, died on Tuesday at the age of 89, according to a statement from Bogart’s estate.

“With deep sorrow, yet with great gratitude for her amazing life, we confirm the passing of Lauren Bacall,” read the brief but classy line, posted to Twitter with a picture of Bacall accepting an honorary Oscar in 2009.
