LATEST: Janet Jackson has broken her silence to fire back at allegations she has a secret teen daughter.

On Friday (21OCT05), YOUNG DeBARGE, the brother of Jackson's ex-husband JAMES DeBARGE, said in a radio interview to promote his album that Jackson and his brother had an 18-year-old daughter named RENEE.

The teens' existence was kept secret for so long because she had been raised by Jackson's older sister REBBIE, Young DeBarge told New York radio station Hot 97.

But in a terse statement released to US TV show ACCESS HOLLYWOOD, Jackson hits out, "I do not have a child and all allegations saying so are false."

Jackson family attorney Brian Oxman admits the story first came up a few years ago and he asked his clients then if there was any truth to the allegations.

He says, "The answer is no way, no how. From the sisters to the mother, every last one of them said it never happened."

Jackson and James DeBarge, a singer in the former R+B family group DeBARGE, were married for three months in 1984, when Jackson was just 18.

Jackson secretly married RENE ELIZONDO JR in 1991. They separated in 1999. She is now dating rap mogul Jermaine Dupri.
