London: Pop star Rihanna`s brother Rorrey Fenty says she may be the coolest person in the music industry, but she was known for being extremely intelligent at school in Barbados.
"We worked very hard and took it really seriously. We went to good schools and Rihanna was a good student," the 22-year-old Rorrey told dailystar.co.uk.
He added that she was very self-motivated and made sure she only took time out to have fun once a week.
"She is very self-motivated so mum did not have to push her to do homework. She had a lot of discipline. We only went to the beach on Sundays," he said.
Rorrey says the 24-year-old was obsessed with finding unidentified flying objects.
"We used to spend all weekend watching movies and talking about UFOs, looking out for them. Ri really believes there are UFOs," he said.
