Janet Jackson, 50, on doctor-ordered bed rest ahead of baby's birth

For once in her life, Janet Jackson is not the one in "Control."

Doctors have ordered the pregnant pop star, 50, to remain in bed, according to multiple reports.

A source told E! News that Janet is now under "doctor's orders to rest" until her baby arrives.

"She is doing okay and resting until she is due for her baby," the source told E!, explaining that the order came after Janet experienced some unknown pregnancy complications.

But no one needs to worry. "As of now, doctors say she is okay," the source added.

Us Weekly is also reporting that Janet -- whose happy baby news was confirmed in May -- is "on bed rest" per doctors' orders, said an insider.

"She's where all of her doctors are," the insider added. "But she had taken her mother out to lunch a few weeks ago."

This will be Janet's first child with husband Wissam Al Mana, 41, whom she secretly married in 2012.

Speculation that Janet was expecting first emerged in April when she cancelled the rest of her "Unbreakable" world tour.

"We're in the second leg of the tour and there actually has been a sudden change. I thought it was important that you would be the first to know," she said in a Facebook video post. "My husband and I are planning our family, so I'm going to have to delay the tour."

In May, a Jackson relative told Page Six that Janet's mom Katherine Jackson pressured Janet to try to start a family with her husband despite her advanced maternal age.

"[Katherine] said to Janet, 'You cannot afford to wait too much longer. I was already a grandma at your age,'" the relative explained.

Katherine, 86, is said to be "thrilled" over Janet's pregnancy and the fact that this baby will make her a grandmother for the 28th time.

"It would mean that all of her children have given her grandchildren," the relative added. "She hopes that she can be in the room when Janet gives birth."

The most remarkable thing about Janet Jackson is not her music, her style or her films. It's the fact that the youngest of eight children who grew up in the shadows of her incredibly famous brothers was able to break out and not only build a career separate from the juggernaut that was "The Jacksons" but become a music legend in her own right. To mark Janet Jackson's 50th birthday on May 16, here are some things you might not know about the second most famous member of the Jackson family.
