The 24-year-old "Umbrella" hitmaker was very disciplined and had a thing about discovering life beyond Earth during her childhood days, Rorrey said, reported Contactmusic.
"We worked very hard and took it really seriously. We went to good schools and Ri was a good student. We used to spend all weekend watching movies and talking about UFOs, looking out for them. Ri really believes there are UFOs," he said.
The 'Where Have You Been' hitmaker's little brother is also launching a rap career.
