Janet Jackson is canceling the rest of her tour to have a baby ... maybe.
Janet posted a video message to her fans saying she was pulling out of her Unbreakable tour dates because she and her husband are planning a family.
She says she's under doctor's orders to rest ... which certainly makes you think she's trying to, or already is pregnant. Janet never says one way or the other. She's 49 (going on 50), so even with IVF ... it would be quite a miracle.
Check out the video ... Janet promises she's not done performing, but a baby -- her first, btw -- might have something to say about that.
