Baby Bombshell! Janet Jackson's Ex Claims In Open Letter That She Secretly Gave Birth To Their Baby

Janet Jackson has sensationally been accused of faking a pregnancy at 50 — but she's hiding another baby secret dating back more than 30 years!

With insiders whispering there's no way Jackson is actually expecting, her ex-husband, singer James DeBarge, is pleading to finally reunite with the child he says she stole from him in 1984!

"Janet has always kept things hidden, so none of this should surprise anyone," dished a source.

DeBarge, 52, was married to Jackson from 1984 to 1985. But her family pushed them into having the union annulled, and he's long suspected Jackson hid a pregnancy from him during the '80s.

Now RadarOnline.com can reveal a passionate letter DeBarge has written to Jackson, begging her to acknowledge bearing his child!

"I don't want to live the rest of my life not knowing the truth!" DeBarge wrote. "I know you have enough money to keep this secret from the whole world. The one thing I learned from you and your family is how much money can buy and keep a secret."

The "Rhythm Nation" singer is worth an estimated $175 million, while her third husband, 41-year-old Qatari businessman Wissam Al Mana, is worth a staggering $1 billion.

And in the ultimate sign of "Control," Jackson has only been seen once since news of her pregnancy was revealed.

The Grammy Award-winning hit-maker announced on April 6 she and her husband were "planning our family," and she was scuttling her concert tour on "doctor's orders."

But DeBarge insists Jackson already has a child — and someone claiming to be that daughter has reached out to him.

"She spoke to me by e-mail and everything she said was so accurate," he revealed. "It was only things that Janet and I know."

Now he's desperately hoping Jackson will confirm if the woman is his daughter.

"I swear, I won't cause you any trouble," he wrote to Janet in his impassioned plea. "I don't want any money. I just want her to know I'm her father!"
