Rihanna's brother Rorrey has revealed she used to be one of the smart kids at school.
The 'Where Have You Been' singer's little brother, 22, admitted that she may be the coolest person in the music industry at the moment but she was known for being extremely intelligent at school in Barbados.
Rorrey Fenty told the Daily Star newspaper: "We worked very hard and took it really seriously. We went to good schools and Ri was a good student."
He added that she was very self-motivated and made sure she only took time out to have fun once a week.
He said: "She is very self-motivated so Mom didn't have to push her to do homework. She had a lot of discipline. We only went to the beach on Sundays."
Rorrey, who is launching a rap career under the name GQ, also revealed that the 24-year-old was obsessed with finding unidentified flying objects.
Apparently the performer had a thing about discovering life beyond Earth.
He continued: "We used to spend all weekend watching movies and talking about UFOs, looking out for them. Ri really believes there are UFOs." - Bang Showbiz
