Janet Jackson gives birth to son at age 50

Washington: Pop superstar Janet Jackson gave birth to her first child at age 50 on Tuesday, according to US media.

Jackson and her husband Wissam Al Mana, a Qatari businessman, welcomed their son Eissa into the world after a "stress-free" delivery.

"Janet had a stress-free healthy delivery and is resting comfortably," the singer's spokesperson told People Magazine.

The younger sister of late king of pop Michael Jackson in April stunned fans by halting a global tour and saying that she and her husband were "planning our family."

Natural pregnancies are highly unusual, but not impossible, for women past their mid-40s, but in vitro fertilization can extend the age at which women can have children.

In October, People Magazine published a photo of the middle-aged celebrity on the beach holding her baby bump.
