It's another day in the fab life of the celebrity: things to do, places to be. Dita Von Teese and "the girls" promoted the Wonderbra in London, just about the same time Jessica Simpson arrived in the UK with her groupie father. Also landing in Heathrow was Lily Allen, for whom camera-shy was an understatement. Hiding under a sweatshirt, she was anything but fashion savvy, unlike Sienna Miller, who dressed in Vuitton to walk her dog. Back stateside, Khloe Kardashian hit up Williams-Sonoma (possibly wedding registry shopping?) with her mother Kris, before meeting sis Courtney and Courtney's baby daddy Scott at Kitson kids. Far from the reality fluff were filmmaker siblings Joel and Ethan Coen, stopping at the Apple store in SoHo. Also doing something hinting of thought stimulation was Michael Moore, who was rallying Workers Against Capitalism, also in New York. Busy, busy!
