Janet Jackson's Back On The Road

Janet Jackson's mysterious illness, which caused her to cancel or postpone six shows on her Rock Witchu tour, has finally been revealed as vestibular migraines, a rare form of headache that can cause vertigo. "Janet wanted very much to resume her tour so as not to disappoint her fans, but she continued to suffer from vertigo and could not perform," Kenneth Crear, the singer's manager, said in a statement. Janet is planning on performing tonight in Washington, D.C., her manager said, followed by eight more concert dates.
