Ferdinand said: "It was like a drama school but you had to take part in ballet as well. I never admitted that as a kid but now I'm older I can admit something like that.
"I've always been involved in performing arts and, hopefully, in some shape or form, ballet has helped me - you've got to have balance to stay on your feet well.
"I've always been interested in the performing arts. I love music and I love performing. I probably would have done something like that if I didn't play football, I was really into drama at school."
Ferdinand, 26, revealed his hidden talents at the launch of White Chalk Music, a new record label he has set up with business partner Courtney Richardson.
