The Oscar winner, 38, is reminding her fans to never give up on a childhood dream with her latest Instagram post. Portman recently shared an excited photo after receiving a special package in the mail: a Baby-Sitters Club book signed by author Ann M. Martin. “I read every single Babysitter’s Club book when I was a kid. Once when I was 9, I waited in line for 4 hours at my local bookstore to meet Ann M Martin. And today I got this in the mail from her,” Portman wrote in the caption.

And decades later, she still connects with the characters she grew so close with in her youth. “I still identify as a Kristy mixed with Stacey and a dash of Dawn. Which babysitter are you?” she asked fans. “Stacy!!!!!!! Was obsessed,” Pretty Little Liars actress Ashley Benson replied. Other stars chimed in on Portman’s post to share their excitement. “This is huge,” said Mindy Kaling, while Kat Dennings commented, “O DAMN.” Julianne Moore even chimed in with a string of three heart emojis.

The beloved ’80s books are set to get their own TV series; Netflix announced in February that it’s creating 10 episodes based on the franchise. So far, Alicia Silverstone has signed on to join the cast — but no word yet if Portman will be taking part.
