Janet Jackson 'pregnant with first child'

The 49-year-old singer - who will turn 50 on May 16 - is expecting her first child with husband Wissam Al Mana, according to Entertainment Tonight. 

The report of Janet's pregnancy comes just one month after she postponed her world tour because she is "planning a family".

She said in a video message to fans: "Hey you guys, on August 31 I launched the 'Unbreakable world tour. 

"First I want to thank all the fans for coming out and seeing the show, you guys made it so enjoyable each and every night.

"We are in the second leg of the tour and there's been a sudden change and I thought it was important you be the first to know.

"My husband and I are planning a family so I'm going to have to delay the tour.

"Please, if you can, try and understand it's important that I do this now, I have to rest up, doctors orders, but i have not forgotten about you, I will continue the tour as soon as I possibly can (sic)."

She previously postponed 29 US dates on the tour after being advised to have surgery and rescheduled them for July and August. 

In announcing the postponement of the US tour, Janet appealed to her fans for prayers.

She said on her website: "Hey you guys...Happy Holidays to each and every one of you! I need you to know, I learned today, from my doctors that I must have surgery soon.

"It breaks my heart to tell you that I am forced to postpone the 'Unbreakable Tour' until the spring.

"Please pray for me, my family and our entire company during this difficult time...There will be no further comment."
