Vivian Rubio was born in Caracas, Venezuela, to a Venezuelan housewife mother and a Cuban business owner father. She was the youngest of two sisters, and her family had a mixed heritage with some ancestors of Spanish descent. As a child, Vivian was inquisitive and had a distinct ability to empathize with others through emotions. She was also always inclined towards the arts, from singing to dancing to performing, often entertaining her family as the household's comedic relief. Additionally, Vivian was an excellent student academically and was always motivated by competitions, often bringing home a few medals.

In 1993, when Vivian was still a young child, her household faced financial difficulties that inspired her to use her knowledge and abilities to help the family by selling handmade goods and traditional foods. For the next seven years, the family faced progressive financial instability, but eventually, they were given the opportunity to immigrate to the United States in the early 2000s.
