Tallulah Willis, 18, took part in her high school graduation ceremony at an undisclosed school in Los Angeles Thursday.
Her celebrity parents Bruce Willis and Demi Moore were on hand to watch their daughter received her diploma.
Moore, looking fit and thin, arrived wearing dark glasses and a sleeveless black mini dress with a fitted bodice.
Also watching from the audience were her older sisters Rumor, 23, and Scout, 20.
Rue hit Twitter to share a photo that she captured during the milestone event. She tagged it: “My baby sis graduating.”
Demi’s middle child flew in from New York City where she attends Brown University.
Scout picked up some unwanted publicity last week after being arrested for underage drinking and using a fake ID.
