Janet Jackson has announced she is delaying her Unbreakable tour because she and her husband are "planning their family".
The 49-year-old singer - who married businessman Wissam Al Mana in 2012 - posted a video on her Twitter account to announce the news.
Jackson did not say that she was pregnant but said there had been a "sudden change" to the second leg of her tour, which started in August 2015.
She said she has to "rest up", explaining that it was "doctor's orders".
In the one-minute, 46-second video clip, Jackson asked her fans to understand that it is important she "does this now" and thanked them for their love and loyalty.
She went on to thank her dancers, her band and her crew. She said she could not wait to get started on tour again.
In December last year, Jackson announced she was postponing her Unbreakable tour until the spring to have an unspecified surgical procedure.
At that time, Jackson's statement asked for prayers of support and said no further details on her medical condition would be disclosed.
