We've watched Janet Jackson grow up, but we reportedly missed something -- her being pregnant and giving birth to a daughter.Janet's former brother-in-law, Young DeBarge, the brother of James DeBarge, who Janet was briefly married to in 1984, told a New York radio station that Janet and his brother are parents of "Renee," an 18-year-old girl who is being raised by Janet's sister, Rebbie. "James and the Jackson family kept everything real close, real tight," Young said of James and Janet's relationship. "They weren't very revealing about what the relationship was about." He added that he believes Renee resents the fact that her mother doesn't acknowledge her. "She hasn't really revealed that, but I'm sure that there's some feelings there. It's only natural that you wonder about what it is and how it's come to be that way."When asked for a comment, Janet's spokesperson reportedly didn't deny the claim. Instead, she said that her client had no comment. But Young's remarks support rumors that have circulated for years claiming Janet has a secret daughter.Janet was 18 years old when she and James got together. They eloped in 1984, but annulled their marriage in 1985. Janet, who is good at keeping secrets, was also married to Rene Elizondo from 1991 to 2000. After Janet announced they "broke up," Rene came forward and revealed that they hadn't been dating -- they had been married. Janet is currently dating producer Jermaine Dupri. I think. For all I know she could secretly be married to him as well.Child molestation charges. Nipplegate. A secret marriage. A secret child.
