She is out of the hospital, but Janet Jackson’s recovery from an unknown illness is forcing her to postpone two dates on her “Rock Witchu” tour.

Janet’s concerts in Boston (Oct. 1) and Philadelphia (Oct. 2) will be rescheduled, the star’s rep tells ET. The tour will resume in Greensboro, NC, this Saturday, Oct. 4.

On Monday, the 42-year-old singer suddenly fell ill before a scheduled concert in Montreal and was rushed to a hospital earlier in the day during a soundcheck. Info on the rescheduled concert dates will be released as soon as possible. I want to see her next time around in Toronto.
