Hill's longtime boyfriend Rohan Marley, son of reggae legend Bob Marley and the father of Hill's five other children, has reportedly dumped her for Brazilian supermodel Isabeli Fontana.
Fontana, the 28-year-old Victoria's Secret model at the center of the triangle, has done little to discourage the rumors. On July 20, she posted a picture of her and Marley on Twitter, along with the message "I'm in love with @Romarley's heart."
Marley, 39, hasn't exactly denied the relationship either, as he retweeted the message. Nor has he confirmed his split with Hill.
"Ms. Hill is the mother of my children, whom I have a tremendous amount of love and respect for. I would never do that," he tweeted, perhaps in response to the rumors that he'd dumped the pregnant mother of their five children.
"The nature of our relationship is something we don't expect people who spread gossip for a living to fully understand," he continued in the tweet.
After Hill gave birth to her sixth child Saturday, Marley posted a message saying, "I'm forwarding all well wishes to Ms. Hill on the birth of her new son."
Saturday's birth was not without complications. A source told BlackCelebKids that although "mother and baby are fine," the little boy was delivered with the umbilical cord wrapped around his neck.
Hill, 36, the former Fugee frontwoman and winner of five Grammys, still hasn't revealed who the baby's father is. A source told CNN that Hill is calling the baby "Baby Boy Marley."
Marley, however, seemed to cast doubt on whether he was the dad during a Twitter exchange with a Houston Chronicle reporter.
The reporter wrote: "So we are clear. 1.) You're not married to your ex-wife or Lauryn, and 2.) She isn't preggo w/your child, but someone else's?"
Marley's response: "That is correct until I say out of my mouth to the contrary."
Hill also seemed to hint that the announcement of the mystery baby daddy would be a shocker. After surprising a concert audience in Detroit with the news that she was expecting, she said, "Wait till you hear the big secret, though."
In the middle of all this baby drama between Hill and Marley is Fontana, a Vogue cover girl, a star of H&M ads and Victoria's Secret runway model.
Fontana, a native of Brazil, is twice-divorced and has a son from each marriage. Ironically, her oldest son is named Zion, the same name as Hill's first-born son with Marley and the subject of Hill's hit song "To Zion."
The drama continues.
