>> Siri Tollerod, Dree Hemingway Both Go Blonder —Yesterday, Siri Tollerod turned up at Zac Posen and then again at Marc Jacobs with substantially lighter hair than the day before; looks like she's jumped on the platinum blonde bandwagon, as her agency just posted photos of her with the lighter shade.  And Dree Hemingway, too, was sporting a blonder look than usual when she turned up at the Jane Hotel to party with Another Magazine last night.
