She attended Les Cours Sonou University and received a BA degree in international relations and "political science". During her college years, she was often bullied by her classmates because of her age and appearance. To counter the feelings, she experienced from being taunted, Starr turned to music. "I would listen to Nicki Minaj on my way to school and I'd feel like the second Nicki Minaj."
