Janet Jackson has postponed her “Unbreakable” tour again, saying that doctors have ordered her to rest and prompting speculation that she might be pregnant.

“We’re in the second leg of the tour, and there actually has been a sudden change,” she said in a video on Twitter Wednesday morning. “My husband and I are planning our family. So I’m going to have to delay the tour.”

Jackson, 49, married Qatari businessman Wissim Al Mana, 41, in 2012. “Please, if you can try and understand it’s important that I do this now,” she told her fans. “I have not forgotten about you. I will continue the tour as soon as I possibly can.”

Jackson was scheduled to perform at Nikon at Jones Beach Theater on June 25 and Barclays Center on Aug. 15, a date that had already been postponed once after Jackson pushed back her tour last year so she could have an unspecified surgery. It is not clear when the dates will be rescheduled.

Jackson’s “Unbreakable” tour, her first in four years, began last summer, but was suspended in November for health reasons that she did not disclose.

In the video, Jackson said fan support helped her through the issues. “Thank you to all the fans for your love, your undying love, your loyalty, that means so much to me,” she said. “You are truly appreciated and it’s been a long journey, and you guys have been there each and every step of the way.”
