Somewhere, an MTV executive is kicking himself for not putting a divorce clause in the reality show contract of "Meet the Barkers" stars Travis Barker and Shanna Moakler, whose increasingly sordid split has all the makings of an addictively trashy soap opera. The latest salvo comes courtesy of one of the ink-stained rocker's pals, who puts the blame for the split on Shanna, tattling to the New York Post that she "is never home ... She parties every night, sleeps until 1 p.m. every day and doesn't spend nearly enough time with the kids. And on top of that there have been rumors she hasn't been faithful. He's had it." Confirms Barker through his mouthpiece, "I'm sad to say those allegations are true ... My priority will remain my children." But a miffed Moakler, who has two kids with Barker (son Landon, 2, and daughter Alabama, 7 months), fires back through her rep, insisting to the paper, "I have been 100 percent faithful in my marriage and a devoted mother, two facts of which Travis is well aware. I still happen to be very much in love with Travis, and his using the media to take low blows at me isn't just embarrassing, it's hurtful. I feel he should be putting his family first instead of his pride." Snits an unmoved Barker, "The truth will prevail."

Does Paul McCartney's daughter Stella want him to take a breather from his tabloid-bait divorce battle with Heather Mills to go out on a date? That's the claim being made by the London Sunday Mirror, which says the ex-Beatle's fashion designer offspring wants to set him up with Blythe Danner, the mom of her bestest pal Gwyneth Paltrow. "Stella fully realizes that the last thing her father needs right now is a new woman in his life, especially in the midst of a messy divorce," a "close friend" tells the paper. "But Stella knows that he'll want and need a woman in his life again. She thinks someone like Blythe will be ideal." One sad bit of common ground that Paul, 64, and Blythe, 63, share: They've both lost a spouse to cancer. Linda McCartney, Paul's wife of 29 years, died of breast cancer in 1998, while Bruce Paltrow, who was wed to Blythe for 32 years, passed away from throat cancer in 2002.

Ethan Hawke doesn't have to worry about whether his new squeeze will cotton to his two kids. People reports he's quietly seeing a "mystery woman" who once worked as their nanny. A source describes the former caretaker as "lovely, smart and well-educated," and insists the romance is "all very aboveboard" (translation: please refrain from any untoward Jude Law comparisons). Seems Ethan fell out of touch with his former employee in 2004 after his breakup with Uma Thurman, but reconnected with her this summer after a fortuitous meeting.

Is Jessica Biel an equal opportunity busser? The New York Daily News says the brunette hottie raised eyebrows last week at New York hotspot Lotus when she gave some sugar to "an attractive female companion." But Jessica's rep, who was tagging along on the club outing, maintains to the paper that the kiss-and-tell tale is so much fiction.

Lance Bass is brushing off talk that he and boyfriend Reichen Lehmkuhl are speeding towards splitsville. "We are very happy," insists the ex-boy-bander to People. "It's nice to be able to go out and be yourself." Adds Lehmkuhl, "We love to keep it mellow. It's really nice right now to enjoy private time together. We're just normal like anybody else, [going to] the beach, movies, the pool." Rumors of trouble began just days after Bass came out to the mag and talked up his "very stable" relationship with the reality show winner-cum-model-actor-author.

Is there anything sadder than a single supermodel? London's News of the World says Elle Macpherson has ditched real estate mogul beau John Hitchcox after just three months of togetherness. Good thing she has other matters to occupy her mind, like duking it out with Victoria's Secret spokesmodel Heidi Klum over who owns the nickname "The Body." Fumes Elle's rep to the New York Daily News, "In terms of public record, that name belongs to Elle."

Stephen Baldwin is doing his part to make sure no one ever enjoys a ménage à trois again. "I like to ask friends of mine, happy couples who seem to have a pretty good marriage, I will ask them, 'How's your sex life?'" the conservative, Christian-boosting Baldwin brother writes in a new book, excerpted in Esquire (via the New York Daily News). "They will say something like pretty good or okay or no complaints here. Here's what I tell them: Imagine taking a healthy sex life and inviting the power of God into that exchange." And what a power it is, according to Baldwin, who enthuses, "I'd always imagined Jesus was the sweet, cuddly, loving dude, and suddenly I find out he makes Conan the Barbarian look like Conan the Wimp."
