Tallulah Willis is getting candid about her journey.

The 30-year-old shared her autism diagnosis March 16 with a heartwarming, throwback video of her and dad Bruce Willis.

In the video, Tallulah—whose mom is Demi Moore—is seen playing with the actor's head and ear as he holds her. As she captioned the post, alongside the laughing crying emoji, "Tell me your autistic without telling me your autistic."

And, when a user asked whether she'd been diagnosed as a child, she explained, "Actually this is the first time I've ever publicly shared my diagnosis. Found out this summer and it's changed my life."

Afterwards, older sister Scout Willis, 32, showed her love commenting, "She's stimming." (Stimming refers to self-stimulatory behaviors, like the repetitive movements Tallulah shows in the clip.)  

To which Tallulah wrote back, "Dude the ear curl. I wish we had better audio."

The throwback video strikes an especially poignant chord amid Bruce's ongoing battle with frontotemporal dementia. Since announcing his diagnosis with aphasia in 2022, and then with the more specific diagnosis of frontotemporal dementia in Feb. 2023, the Die Hard actor has taken a step away from the spotlight.

Throughout it all, Bruce's family—which also includes Tallulah's older sister Rumer, 35, as well Bruce's wife Emma Heming Willis and their daughters Mabel, 11, and Evelyn, 9—have open about his health journey.

"There is grief and sadness," Emma has previously shared. "There is all of that. But you start a new chapter and that chapter is filled. It's filled with love. It's filled with connection. It's filled with joy. It's filled with happiness. That's where we are."

And some of that joy and happiness involves celebrating as a family, which is exactly what they did for Tallulah's 30^th birthday in February.

Demi shared a peak into the milestone celebration with a picture of herself and Bruce posing with their daughter. The Ghost actress captioned the Feb. 3 post, alongside a heart, "Showering our @buuski with love today on her 30th birthday."

Love is a beautiful thing," the actor's wife Emma Heming Willis wrote on Instagram, almost exactly one year after his family announced his frontotemporal dementia diagnosis. "Wishing you all a Happy Valentine’s Day."

In February 2024, Demi Moore shared this pic of her ex-husband with the youngest of the three daughters they share together, writing, "Showering our @buuski with love today on her 30th birthday."

In November 2023, the actor celebrated his first Thanksgiving since being diagnosed with frontotemporal dementia earlier that year. His wife Emma Heming Willis shared this photo from Bruce's 68th birthday party from March.

"I’m grateful and thankful to know this kind of love," she wrote. "Wishing you all a Happy Thanksgiving."
