Millie Bobby Brown still remembers what it was like to have financial insecurity.

The 21-year-old “grew up with no money” before receiving the life-changing call that she had been cast on Netflix’s “Stranger Things.” In an appearance on the “Call Her Daddy” podcast, Brown said that her upbringing has had a profound effect on how she thinks about her finances.

“I have a money thing where I’m very conscious about money,” she said. “When I do spend money on something, I have to call my parents; I have to think about it; I don’t just buy it right away.”

That’s not because money is in short supply. The “Electric State” star was reportedly earning $10 million per film as early as 2019 and has a “ridiculously lucrative” overall deal with Netflix, according to Puck.

But just because she has the money doesn’t mean she has champagne tastes. Compared to her husband Jake Bongiovi—son of musician Jon Bon Jovi—Brown said she is very thrifty.

“I’ll be like ‘Oh, I need socks,’ and he’ll be like ‘Let’s go to Prada,'” she said. “And I’m like, ‘Let’s go to Target.'”

“‘He loves to go shopping,” she continued. “He will refuse to pack a suitcase because he likes to go shopping in the place we’re going. Whereas I like Amazon Basics. I love that.”
