Before you go, we thought you'd like these...  Just days before Mother's Day, a source confirms to ET that Janet Jackson is pregnant with her first child.  The baby news comes after the 49-year-old singer -- who will turn 50 on May 16 -- announced last month that she will be postponing her tour to start a family with husband Wissam Al Mana. "We're in the second leg of the tour and there actually has been a sudden change," Jackson explained in a video posted to Twitter on April 6. "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."
