NEW YORK (AP) ? Janet Jackson is delaying her "Unbreakable" tour, saying Wednesday she and her husband are planning their family and that she is under doctor's orders to rest. The 49-year-old singer announced in a clip on her Twitter account Wednesday morning that there has been a "sudden change" to the second leg of her tour, which started in August. "We're in the second leg of the tour, and there actually has been a sudden change," a smiling Jackson said.
