Janet Jackson has postponed all upcoming tours as she is planning to become a mother.
The singer’s announcement comes a month after she scrapped concerts in Europe, and affects 55 further concerts in the US and Canada this summer.
Speaking in a Twitter video, Janet Jackson, 49, told her fans: “My husband and I are planning our family – so I’m going to have to delay the tour.
“Please, if you can, try and understand that it’s important that I do this now.
“I have to rest up [on] doctor’s orders. I will continue the tour as soon as I possibly can.”
Janet Jackson went on to thank her “supportive and loving” dancers and musicians, and to her fans for their “undying love” and “loyalty”.
Michael Jackson’s sister, who returned to the top of the Billboard charts in 2015 with her eleventh album, Unbreakable, is married to fashion tycoon Wissam Al Mana.
Although Janet Jackson has been married twice before – to musicians James DeBarge and Rene Elizondo – she has no children.
Her world tour has been beset by health problems.
In December 2015, Janet Jackson postponed 29 US dates after being advised to have surgery. She later denied rumous that she had been diagnosed with cancer.
Before that, the concerts received rave reviews, and were listed as one of the top 20 highest-earning tours in a chart compiled by Pollstar.
