Well-placed sources tell us that pop star Pink's marriage is on its last legs. Apparently, when the singer married her biker beau, Carey Hart, she took a "Don't ask, don't tell" policy and agreed to let him have his fun when she's away on tour. But she's changed her mind now that her biological clock has started ticking. "Divorce is just around the corner," says our mole. "Carey has this one blond in particular that he takes everywhere, even public appearances. But Pink knew what she was getting into!" Stupid girl, indeed.
