Janet Jackson Baby Hoax!?

A picture of Janet Jackson snuggling with three-month-old son Eissa has triggered a bombshell baby scandal — with charges the star is NOT the biological mother of the infant!

"Who is she kidding?! That baby is white!" one shocked fan rails. "There's no way Janet is this baby's mom."

Blasts another: "C'mon folks, seriously?? That child is white. This substantiates the rumors that it was a faked pregnancy!"

The explosive speculation, following Janet's first posting of a photo of baby Eissa, is ­bolstered by the mystery that's surrounded the Rhythm Nation songbird since early April last year.

Janet, who turns 51 May 16, stunned fans by suddenly announcing she was indefinitely postponing her

Unbreakable World Tour because she was "planning" a family with her third husband, Wissam Al Mana, 42, a billionaire businessman from the Arab nation of Qatar.

The revelation was especially stunning because fans thought at age 50, Janet's biological clock had stopped ticking.

Asks another critic, "You have to wonder if she and ­Wissam used a surrogate to carry his child, conceived using a donor egg?

"Or did they secretly adopt? This child certainly doesn't look like Janet's."

Just weeks after Eissa's Jan. 3 arrival, Janet shockingly announced she and Wissam were splitting — even as he posted a heartfelt message: "To the most beautiful person in the world. I love you so much!"
