She grew up around other rappers who later became famous battle rappers. Though she would hang out with them in the studio, she didn't tell anyone she'd been writing raps until she turned 18.
She was introduced to Pharrell by her manager. The rapper asked her to put lyrics to a piece of music as an audition and, after finishing the rap in under twenty minutes, they recorded it and launched her career.
She is of Puerto Rican and Italian descent.
The song she auditioned with for Pharrell was meant for TI but eventually it became her single, with TI on it as a featured guest.
