Anna Wintour's famous bob has been compromised by imitators: Posh Spice, mother-of-the-messiah Katie Holmes and even, lately, the actress' husband, Scientologist preacher Tom Cruise. But we still prefer the original hairstyle, as defined by the legendary Vogue editor, seen here from behind, in a presumptuous shot by Julia Allison. The Star Magazine talking bosom was sitting behind Vogue's Wintour (omg!) at the Oscar de la Renta runway show, yesterday. "It took every ounce of self-control I had not to pet her hair," says Allison. Commenter FLIPPER BABY responds: "Just a little less self-control and we would have gotten footage of Wintour snapping JA's neck with her mind."
