Janet Jackson's been ordered to put her feet up.

The 50-year-old music icon, who is pregnant with her first child to husband Wissam al Mana, is "on bed rest" due to complications, a source told E! Online.

"She is doing OK and resting until she is due for her baby," the source said, adding that: "[Janet] is aware of complications, but as of now doctors say she is OK."

The Escapade singer's pregnancy news was revealed in May, a month after she cancelled her comeback world tour.

"We're in the second leg of the tour and there actually has been a sudden change," Jackson explained in a video posted to Twitter on April 6.

"I thought it was important that you be the first to know. My husband and I are planning our family, so I'm going to have to delay the tour."

Jackson secretly wed al Mana, 41, in 2012, but didn't confirm the news until early 2013.

This is the singer's third marriage. She married James DeBarge in 1984 before having it annulled. She was also married to Rene Elizondo from 1991 to 2000.
