Bella Thorne claims she was left with just $200 by the time she was 18.
The 21-year-old actress began her career when she was just nine years old and starred on 'Shake It Up' for three seasons but insisted she was broke when the Disney show ended.
However, asked where her money had gone, she simply told the Los Angeles Times newspaper: "You know where it went."
The publication suggested the situation could have been connected with the Coogan law, which requires employers to withhold 15 percent of a minor's gross wages, preventing income from going entirely to child actors' guardians.
And Bella admitted she always knew there was something "not right" about her situation, even though she didn't expect it to be so tough.
She said: "I didn't think things were going to go down like that.
"And then half of me is like, 'Come on, Bella. Look at your whole life. Don't be naïve. You knew somewhere deep down inside things were not right.' "
In the candid interview, the 'I Still See You' actress - who has both a boyfriend, rapper Mod Sun, and a girlfriend, YouTuber Tana Mongeau - spoke of how she smokes marijuana to deal with intense emotions, even though she used to be "super against" the "devil's lettuce".
She said: "I used to be super, super against weed. When I was 16, my boyfriend smoked weed and I would get so upset. I thought it was the devil's lettuce. I was always the really good two-shoes -- the one that was the teacher's pet in that annoying sense."
But the actress asked her brother for the drug to help her sleep after she got too emotionally involved with one of her roles and couldn't stop crying and her opinion changed.
Bella, who shares her home with 19 cats, admitted she loves to work because otherwise she ends up in a "weird place".
She said: "My mind is a scary place. I can't leave myself alone too long. My mind goes to a weird place if I'm not at work all the time."
