Janet Jackson Postpones Tour, Includes Tulsa Show

Janet Jackson is delaying her "Unbreakable" tour, saying Wednesday that 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.

Jackson was originally scheduled to perform at the BOK Center in January, but delayed that stop and re-scheduled that show to July 16.  Now, her show is delayed until further notice.

She didn't say she was pregnant with her first child, only that she needed to rest up. The youngest child of the Jackson family, she turns 50 in May.

"We're in the second leg of the tour, and there actually has been a sudden change," a smiling Jackson said. "I thought it was important that you be the first to know.

"My husband and I are planning our family, so I'm going to have to delay the tour. Please, if you can, try to understand that it's important that I do this now. I have to rest up; doctor's orders. But I have not forgotten about you."

Jackson married Wissam Al Mana in 2012. It is her third marriage.
