NEW YORK (AP) -- Janet Jackson and James DeBarge, who were briefly married in 1984, had a daughter together, DeBarge's brother Young DeBarge has claimed on a radio program.

Young DeBarge said the child, named Renee and now 18, has been living with Rebbie Jackson, Janet's oldest sister. His comments lent support to reports that have circulated for years claiming Janet has a "secret" daughter.

Jackson's publicist didn't immediately return a call from The Associated Press on Monday, but Brian Oxman, an attorney for the Jackson family, told E! Online that he asked the Jackson family years ago if the story was true.

"The answer is no way, no how," he told E! "From the sisters to the mother, every last one of them said it never happened."

Jackson, 39, secretly married Rene Elizondo Jr. in 1991. They separated in 1999. She is now dating Jermaine Dupri.
