In an emotional Instagram post back in 2013, Rita Ora paid tribute to her grandfather, Besim Sahatciu. "I miss you grandad....Besim Sahatciu. I love you. You made me believe this was possible. Your stories your movies we had so much fun dressing up. You believed in me before I even did. Dam you were such a Gangsta. Don't get into any trouble up there. Love Rita Pita". Although not sure where the actual nickname comes from, it has to be the cutest nickname ever!
