Tallulah Willis revealed that she's been diagnosed with autism. The 30-year-old actress and daughter of Bruce Willis shared her health discovery on Instagram over the weekend - amid her father's ongoing battle with dementia. She posted a video of her and her father, who has over the last two years been diagnosed with both frontotemporal dementia and aphasia, on the red carpet at the premiere of the actor's 2004 movie The Whole Ten Yards, which then 10-year-old Tallulah also starred in. With the post, she wrote: “Tell me [you're] autistic without telling me [you're] autistic.” Tallulah wrote: “Actually this is the first time I've ever publicly shared my diagnosis. Found out this summer and it's changed my life.”
