Is Janet Jackson expecting her first child at 49? Singer announces she'll delay her world tour to plan her family

Janet Jackson, 49, took to Twitter this afternoon to announce delay in her world tour to enable her and her husband start a family. She said;

"Hey, you guys. On Aug. 31, as you probably, know I launched the Unbreakable World Tour. First I just want to thank all the fans for coming out and seeing the show. Thank you so much,. 

You guys made it so enjoyable each and every night. We're in the second leg of the tour and there actually has been a sudden change. I thought it was important that you would 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. I will continue to tour as soon as I possibly can."
