Washington, Oct 6 Popstar Janet Jackson has deferred three more of her shows as a result of her undisclosed illness.

Last week, the 'Alright' hitmaker was hospitalised following the illness.

And now, a rep for Jackson's revealed that the singer, 42, postponed a Saturday-night show in Greensboro, N.C., after a local doctor said it was "evident" she had not fully recovered, reports People magazine.

Other shows put on hold were in Atlanta and another in Fort Lauderdale.

Jackson, who is on her first North American tour in seven years, previously cancelled concerts in Boston and Philadelphia. (ANI)
