In the Big Fat Rumor of the Day, the “National Enquirer” is reporting that Usher wants a paternity test done on his youngest child, 6-month-old Naviyd, because he and his soon-to-be ex-wife Tameka were having little to no sexual relations at the time she conceived. “The first thing Usher said was, ‘How did this happen?’ because he was gone a lot, and their sex life was very, very limited,” a friend of Usher told the tabloid. “People have been telling him that around the time the little boy was conceived, Tameka got together with another man.” Tameka, however, claims Naviyd is Usher’s child and says it was Usher who was being unfaithful at the time. “She says that although they weren’t spending much time together, they did get together for one night of passion. And that’s when she got pregnant,” the source said. Meanwhile, E! is reporting that Tameka’s new court filing states she and Ursh have not been separated since July 2008 and, in fact, were “intimately together” less than a week before he started divorce proceedings. She had “every reason to believe her marriage was intact,” her attorney stated in documents filed Monday in Atlanta. Tameka’s filing seeks to ensure that her estranged husband takes care of all of her legal fees pertaining to the split and continues to support his family financially, according to E! Online. Usher filed for divorce June 12, checking off “irretrievably broken” as his reason to end the marriage and requesting joint custody of the couple’s two sons.

We don’t have many details yet, but the “National Enquirer” claims that R. Kelly could be facing yet another underage sex scandal. Supposedly, police investigators showed up at Kelly’s Chicago-area home to investigate a tip that an underage girl was living with him. They found that there was indeed a 17-year-old girl living with Kelly, but 17 is the legal age of consent in Illinois. So that in itself isn’t a crime. The investigation isn’t necessarily over, though. Police are now trying to determine the nature of Kelly’s relationship with the girl, and how long it’s been going on. Kelly, who’s 42 years old, is currently on tour in South Africa, and will be questioned when he returns. R. Kelly’s people are flat-out denying this entire story. Kelly’s rep says, “A wildly exaggerated and inaccurate report has been circulating on the Internet that Olympia Fields police showed up at R. Kelly’s house with a search warrant and searched the place looking for a missing 17-year-old girl. This is completely false. No police ever showed up at Kelly’s house with a search warrant nor was his house ever searched. It is also not true, as the unsubstantiated report claimed, that any such girl ever stayed overnight in Kelly’s house or that she had been there but left shortly before some mythical police search.” Last year, Kelly was acquitted of various charges for allegedly videotaping himself having sex with a girl who may have been as young as 13 or 14. Back in 1994, Kelly married Aaliyah. She was only 15 at the time. The marriage was annulled within a year. Kelly has also settled out of court with three women who sued him, claiming he had sex with them when they were underage.

Kevin Jonas is engaged! Yesterday morning, Kevin showed up at the doorstep of his girlfriend, Danielle Deleasa, in New Jersey and popped the question.  And yes, he did indeed get down on one knee. Kevin says, “She said ‘Yes, yes, yes,’ like 500 times super fast in a row.” Kevin actually flew to New Jersey from Vancouver, where the Jonas Brothers had just performed the previous night. Kevin says, “It was tough performing knowing that I was going to ask the biggest question in my life to the most amazing girl in the world.” Kevin and Danielle met in May of 2007, while vacationing with their respective families in the Bahamas. At the time, Danielle claims she didn’t even know who the Jonas Brothers were. Kevin is 21, Danielle is 22.  There’s no word yet on a wedding date.

Hilary Duff will guest star on a few episodes of “Gossip Girl” this fall. According to “Entertainment Weekly”, she’ll be playing Olivia, a movie star who enrolls at New York University to enjoy a “normal” college experience. She’ll be rooming with Jessica Szohr’s character, Vanessa. If you’re a “Gossip Girl” nut, it sounds like she may hook-up with Dan, Penn Badgley’s character. Supposedly, he’s into her, but doesn’t know she’s famous. Word has it she’ll be doing a “multi-episode arc” on the show, but it’s unclear exactly how many episodes that run will include. She’ll first appear in the fourth episode of the season, which is scheduled to air on October 5th. Earlier this year, Hilary was developing a series called “Barely Legal” for NBC. It was described as a legal version of “Doogie Howser, M.D.”. But NBC eventually passed on it.
