This is it for Janet, LaToya

Sisterly feud surfaces in arguments over Michael's kids

More raw emotion in the Jackson family: I've learned that Janet and LaToya Jackson got into expletive-filled screaming matches in three separate phone calls this week.

Janet is furious about LaToya continuing to give press interviews about Michael, his kids and the "This Is It" film. According to a reliable family insider, Janet "is sick and tired of LaToya's insatiable need to in the spotlight," and is particularly angry about LaToya's comments about the kids "being in therapy," when they merely had some grief counseling to deal with the shock of their father's death.

While the children understandably deeply miss Michael, "they are coping extremely well," says the source, who adds LaToya is "insanely jealous of Janet," especially since Paris, Prince Michael and Blanket have made it clear they want Janet, and not LaToya or another family member, to be named successor guardian for them upon Katherine Jackson's death.

MOVIE SCHMOOZE: The next film that director George Tillman Jr. and Robert Teitel make here is likely to be a big-screen take on Julia Wertz's book I Saw You: Comics Inspired by Real-Life Missed Connections.

The comedy, about nearly missed romantic connections posted on Craigslist, will be made by Tillman and Teitel's State Street Pictures -- which recently added Chicagoan Matt Pritzker as a partner. He will serve as one of the upcoming film's executive producers. But before the Wertz project, Tillman will direct and Teitel will produce "Faster," starring Dwayne "The Rock" Johnson, followed by a film about surfer Bobby Martinez.
