It seems Janet Jackson has been feeling really nasty these days.
The 42-year-old singer postponed two concert dates this week on her nationwide Rock Witchu Tour due to an "undisclosed illness", a rep for the singer said Tuesday.
She also delayed her Wednesday show in Boston and a Thursday performance in Philadelphia until further notice. Her reps, though, say she will resume her tour on Saturday in Greensboro, NC.
She was hospitalized at Royal Victoria Hospital in Montreal for two hours after bailing on her show just minutes ahead of showtime.
She was released a couple of hours later. The nature of her illness wasn't reported.
