Is Uma Thurman being wooed by Elle Macpherson's baby-daddy? That's the word from the New York Post, which says the willowy actress is seeing Arpad "Arki" Busson, a filthy rich Swiss financier who fathered two sons with Macpherson before their relationship imploded in 2005. Thurman, whose capricious romance with hunky hotelier Andre Balazs went belly-up in March, supposedly sparked to Busson while they were in Rome last month for a Valentino soiree, where she posed with Elle on the red carpet. And it appears Uma and Arki (hee) are seriously smitten, because they aren't exactly shying away from public displays of affection. They were snapped smooching up a storm last week in New York.

Just two weeks ago, Kate Hudson's rep denied she was hot and heavy with onetime "Punk'd" rapscallion Dax Shepard. But their continued coziness has convinced Us Weekly that the actress has rebounded from her May bust-up from Owen Wilson and is "definitely dating" the comedian. According to the mag, the incontrovertible romantic evidence includes "prolonged hugs," hand-holding, romantic lunches, motorcycle rides a deux and sleepovers at Kate's place.

There's nothing like an expensive diamond sparkler to show the mother of your baby that you appreciate all the pain, swelling and stretch marks she's endured over the last nine months. According to In Touch, Naomi Watts has received a Neil Lane-designed diamond-and-platinum heart locket from longtime love Liev Schreiber following the birth of son Alexander on July 25. "It was a very special gift for her," a source tells the magazine. "Liev helped Neil with [the design] after hours." The locket will reportedly house a picture of their bundle of joy.

The bad buzz is growing louder around Jessica Simpson's "Working Girl" rip-off homage "Blonde Ambition," which last month was rumored to be heading straight into turkey territory. But could it also be heading straight to DVD? So says Us Weekly, which reports the flick, produced by Simpson's dad Joe, is too much of a "stinker" for domestic release. "The movie is absolutely horrible," says a spy (a claim that's easily believable to anyone who's seen the execrable trailer, in which Simpson can barely emote her way out from under her curly blond wig). "It's just a bomb -- mainly because of Jessica's acting." The starlet's rep, however, insists it's "definitely a theatrical release," although a studio spokesman says "final distribution plans have not been confirmed ..."

Is there trouble a-brewing for Anne Hathaway and her moneybags beau Raffaello Follieri? The New York Daily News claims the squeaky-clean actress turned on the waterworks during an argument with her businessman boyfriend Saturday night while dining in the Hamptons. "He started telling her off, and she argued back," a spy tattles to the paper. "She rushed to the ladies' room twice, once for about five minutes and another time for at least 10 minutes. She apparently composed herself and came back to the table. Follieri paid the check, and they left." They must have ironed out their differences quickly, however, because later that evening they turned up for a Cinema Society screening of "Becoming Jane," in which Hathaway stars as Jane Austen. "Anne and Raffaello were both at the afterparty and very much together," Society founder Andrew Saffir explains to the paper. "If she seemed emotional, it was because she had not yet seen the film in its entirety, and she found even the little she watched of the opening very moving."

Paris Hilton has some very progressive ideas about how to do her part to save the environment. "I ordered a Hummer hybrid," the jailbird-turned-self-proclaimed philanthropist recently informed Us Weekly. Think the idea of boosting the fuel efficiency of a vehicle designed to be a gas-guzzling road hog is a bit of an oxymoron? You're not alone. A Hummer spokesman tells the mag, "Such a car doesn't exist."
