Is Halle Berry toting home a man or a mannequin? Try neither. "Halle is an avid art collector," her publicist told us last summer, and the stiff figure she carted off from L.A.'s Obsolete gallery is an articulated artist's model from the 1800s. "People used it to sketch from and pose with," says a gallery rep. "It's very rare and very collectible." Though neither would disclose the cost, it is rumored to be $35,000.
