The delightful document-researchers at the Smoking Gun have been on fire today, unearthing a troika of choice New York–tabloid source material. Most prominent is the counter-lawsuit filed by Joumana Kidd in her divorce case against New Jersey Nets star Jason, who is — allegedly, always allegedly — a philanderer so prolific and casual that he discussed extramarital affairs with his son. Less tragic and more comic is the list of accommodations Rudy Giuliani requires for his speaking engagements, including transport on a private Gulfstream IV, for starters — though he’s cool with a bigger plane if you’ve got one. (Also noteworthy: As late as March 2006, months after the Bernie Kerik Homeland Security confirmation mess, the Giuliani Partners email domain was giuliani-kerik.com.) And finally, Foxy Brown somehow managed to get police involved in a dispute over personal grooming. Again. Have fun tomorrow, Post.
