This actress/singer started pretty early in Hollywood. If you didn’t know her first big pay came when she was around nine years old. You can figure that she actually spent her money according to her age. In a statement for People magazine, she said: “When I was 8 or 9, I did a commercial or something, and my parents gave me $200 from it and I took that $200 to Petco and I bought a Betta fish.”
