It's a good time to be a slob. While the compilers of "World's Sexiest Men" lists and the creators of romantic comedies still abide by the notion that the fairer sex unfailingly lusts after clean-shaven, suit-clad men like Hugh Grant, evidence of a shift in the rules of attraction is accumulating. Witness the exquisite Natalie Portman taking a lovers' stroll with matty-bearded freak-folk singer Devendra Banhart, and Kate Moss running from Pete Doherty straight into the arms of Jamie Hince, the greasy-haired guitarist from the Kills. And while she's reportedly moved on, for a time Sienna Miller was dating Rhys Ifans, the slovenly Welshman from Notting Hill.
