The 30-year-old actress said she was diagnosed with autism last summer

Tallulah Willis is opening up about receiving an eye-opening, late-in-life diagnosis.

On Friday, the 30-year-old — who is the daughter of Demi Moore and Bruce Willis — posted a throwback video on Instagram of her as a child attending an event with her dad. In the clip, the Die Hard actor is holding Tallulah during a red carpet interview. As he’s talking, she’s rubbing his head and playing with his ear.

Joking about the moment, she revealed that she was recently diagnosed with autism. “Tell me you’re autistic without telling me you’re autistic 😂” she captioned the post.

In the comments section, one follower praised her for sharing the video and asked if she was diagnosed as a child.

“Actually this is the first time I’ve ever publicly shared my diagnosis. Found out this summer and it’s changed my life. ☀️” Tallulah replied before calling herself “neurospicy” in another comment.

Autism Speaks defines autism spectrum disorder (ASD) as “a broad range of conditions characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication.”

According to the organization, signs of autism usually present around ages 2-3. However, signs can be missed because autism is a spectrum and pediatricians may want to give a patient time to develop before making a diagnosis, the Child Mind Institute states.

Tallulah is often transparent about her health on social media.

Last month, the actress shared an honest post on Instagram about being in recovery from an eating disorder, admitting that she was “romanticizing unhealthy times.” The star first revealed she was dealing with anorexia in a personal essay for Vogue in May 2023.

“I’m having an intense moment of romanticizing unhealthy times and how it felt to move through the day in that size body,” she wrote. “I just wanted to voice it because I know (hope) I’m not alone.”

Her caption was accompanied by a series of photos from her childhood, “This little raggymuffin is so special and it’s strange to know that and want to give her abundance and vitality – LIFE! whilst at the EXACT same moment feeling pulled by an old desire, deep down from the pit spot in your belly, to compare to the ‘better’ version of me. AND it’s ok to be in the middle of the messy and not totally have it all sorted yet. 🫛🌾☀️.”If you or someone you know is struggling with an eating disorder, please go to NationalEatingDisorders.org.
