Goulart was born on October 23, 1984 in São Carlos, São Paulo, Brazil. She is of Italian descent and has four brothers and one sister. Goulart once said "the hardest part about being an Angel is I spend time away from my mom's food and away from my home with my five brothers and sister." School was a particularly rough time for Goulart, as she was made fun of for her skinny build, and was even called names such as "giraffe".
While shopping for groceries with her mother at age 14, a hairstylist suggested that she should become a model. She moved to the state's capital São Paulo and started modeling.
