Stevi Nichole from 90 Day Fiancé is an extremely mysterious personality, and it’s not just her sexuality that should concern Mahdi Al-Saadi. Stevi is a painter from Hattiesburg and an English teacher. She met Mahdi from Iran after he enrolled in her classes to learn conversational English. It didn’t take long for the 37-year-old Stevi to fall for the 26-year-old Mahdi. Stevi flew from Mississippi to meet Mahdi in Turkey, where he proposed to her.
