Now that Diddy has confirmed his split with longtime on-again, off-again love Kim Porter, eyebrows are shooting skyward over his recent chumminess with Sienna Miller. According to the London Mirror, the meticulous music mogul and the semifamous ex of Jude Law hung out together earlier this month at his post-Concert for Diana shindig at a London hot spot, where they were supposedly "flirting in a cozy corner" while six bouncers formed a protective ring around them. But Diddy and Miller, who reportedly met at the Sundance Film Festival in January, a month after the rapper welcomed twin daughters with Porter (she's also mom to his 9-year-old son, Christian), have repeatedly insisted they're nothing more than pals, a stance they have been quick to reiterate in recent days. "There is literally nothing between them," Diddy's rep declares to People, while Miller tells "Extra" she's dating someone new -- and it isn't the rapper. "The amount of people I've been linked to that I've said, 'Hi, nice to meet you,' at a party, and then next minute I'm pregnant with their child," says the exasperated starlet. Diddy, for his part, recently told the London Telegraph, "D'you know that I've never been out with a British woman in my life?"

In other denial news, Rachael Ray is loudly brushing off rumors that her nearly 2-year-old marriage to John Cusimano is about to fall flatter than an eggless soufflé. On Tuesday, the motor-mouthed food maven talked up her domestic bliss to a variety of media outlets. "I don't know where [the rumors] come from; I really don't," Ray sighed to "Extra." "We couldn't be happier." She ups the ante to "Entertainment Tonight," insisting they are "extremely happy" and the split talk is "outlandish" and "ridiculous." Rachael adds to Us that she's not bothered by the speculation. "I don't care," she says. "I still get to go home to my handsome hubby every night. I mean, how dumb would I be to lose that one?" When asked for specifics on what makes Cusimano such a catch, she rhapsodizes, "I mean, he's a lawyer, he cooks and he's a rock star. Is there anything missing? I don't think so!"

Victoria and David Beckham may enjoy showering each other with ridiculously expensive gifts, but even they have their limits. A few days back, the Los Angeles Times reported that the squeaky-voiced soccer stud presented his top-heavy, carb-eschewing wife with a $1.8 million "diamond-encrusted sex toy" while she was pregnant with their third child. Posh, however, pooh-poohs the pricey good vibrations. "We've worked very, very hard to get to where we have, and I think that we do buy each other nice things, but it's never as extravagant as people make out," says Mrs. Beckham (via the New York Daily News). "I think they obviously exaggerate things, so I don't have a diamond-encrusted vibrator. I don't even have a fake diamond-encrusted vibrator." Stars -- they really are just like us.

Anne Heche is refuting allegations made by her estranged husband Coley Laffoon that she not only made off with some furniture and accessories from their Los Angeles abode, but she also attacked some innocent articles of clothing. According to People, Laffoon claims he returned home on July 1 to find the actress had taken an ottoman, a bed and several rugs and had "ripped the buttons off of 19 of my shirts and removed some of my pants." Not so, says Heche, who insists all she left with were four Balinese pillows, some pink bedding and a picture of a saint, all of which she purchased before they said "I do." Meanwhile, could the warring couple's divorce and custody battle escalate even further? The Chicago Sun-Times alleges Laffoon has told pals, ''Anne had better back off or else she's going to be really sorry,'' and has purportedly insinuated that he may "go public" with intimate letters she traded with ex Ellen DeGeneres.
