Now we know why Oksana and Mel fought over her dentist: He was helping her leave her abuser. Kelly Osbourne breaks up with her model boyfriend. Angela Jolie is going to Comic Con. Thursday gossip is in a dark place.

  • Mel Gibson yells at ex-girlfriend Oksana Grigorieva about her dentist in one of their infamous recorded phone altercations, and now we know why: Oksana's dentist was among the few outsiders who knew about the abuse and tried to help her, says an anonymous source. Oksana apparently went to Dr. Ross Shelden—her dentist of twelve years—when Mel hit her in the face and broke two tooth veneers. (One snapped in half, the other knocked off completely.) Shelden needed pictures for her dental records, but Oksana at first refused, saying she wanted to protect Mel. When she relented, "she would not look into the camera." During this incident, Shelden offered to help Oksana flee Mel and said she could stay at his house. Now Shelden is a witness in L.A. County's domestic violence case against Mel.

  • Meanwhile, Oksana's lawyers will go to court today to argue for removing Mel's custody of daughter because he's a violent rage-aholic loon. Mel's lawyers will try to get the phone recordings tossed. [TMZ, TMZ]
  • Speaking of domestic violence: Jaleel White, the actor formerly known as Steve Urkel, will not be charged with domestic battery of his baby mama. Apparently the evidence wasn't strong enough, in part because Bridget Hardy "waited several weeks" between the alleged incident and going to the cops. [TMZ]
  • Angela Jolie is going to Comic Con. She's not in any comic book-related movies, but she basically is a superhero (and has to promote action flick Salt) so it's fine. [THR]
  • Another VIctoria's Secret model is pregnant: Doutzen Kroes, the face of L'Oreal, joins Adriana Lima, Gisele Bundchen, Alessandra Ambrosio, and the perpetually pregnant Heidi Klum as someone whose sexual readiness VS probably wishes they didn't advertise quite so heavily, because now all their models are taking time off.

  • Devon James, the porn star who claims Tiger Woods is her baby daddy—despite the fact that a prior paternity test already proed someone else is—now wears a TIGER WOODS BABY MAMA t-shirt on a daily basis. Low-level fameballs, take note: This is how professional limelight-seekers do it. [TMZ]
  • Kelsey Grammer's divorce from beauty queen wife Camille Donatacci is poised to get ugly: They didn't have a prenup. [TMZ]
  • Joy Behar and Mariska Hargitay went "head to head" over an antique mirror at a store in the Hamptons this weekend. Mariska won. [P6]
  • Perez Hilton reported yesterday that Kelly Osbourne and model fiance Luke Worrall were splitting amid a cheating scandal and a Facebook note that included the sentence "Luke Worall makes me sick!!!" Then Perez removed his post (cached version here) and though Kelly appears to have confirmed the split, though it's "private and [I] will not be commenting." [PerezHilton, People]
