Remember Bjork's outrageous "swan" dress she wore to the 2001 Oscar ceremonies (as if you could forget that)? Well, you can own it if the price is right....Bjork contributed the dress for an auction run by International aid agency Oxfam...."We wanted people to give things that were personal and had a story behind them because bidders will know they're getting something special," said Oxfam spokeswoman Rose Marsh. Other rock related items on the block include Damon Albarn's moped helmet, Yoko Ono's sunglasses, and fashion designer Stella McCartney's fake leather boots....Bidding begins Sept. 18 ... Beck will shoot a video for the track "Hell Yes" in the coming weeks, and it'll feature a special guest. Actress Christina Ricci -- who lent a vocal contribution to the song -- is reportedly appearing in the clip as a Japanese sushi waitress, heard repeating "Please enjoy, please enjoy." ... The newly-blonde Ashlee Simpson is set to perform on The Oprah Winfrey Show sometime in October, to coincide with her sophomore CD release, I Am Me. There were whispers floating around that she'd make a second appearance on Saturday Night Live, but it hasn't been confirmed. Better keep that 'acid reflux' doctor's note handy ... UK megastar Robbie Williams -- still an enigma in America despite his huge international success -- will release his sixth solo album in Europe on Oct. 24, entitled Intensive Care. Williams had been recording the CD here in L.A. for the past two years, but there's no American release date scheduled yet. Robbie describes the lead single, "Tripping," as "something like a mini-gangster opera." ... On Sept. 24, the anti-war coalition Operation: Ceasefire will bring a corking lineup of acts to the grounds of the Washington Monument in D.C. as part of four days of protests organized by United for Peace and Justice. Anchoring the event is Le Tigre, MC5, Thievery Corporation, Ted Leo & The Pharmacists, L.A.'s own Bell Rays, and many more. Jello Biafra will emcee the event and the show is free. This great cause can be supported online at www.opceasefire.com ... And finally, bets are being placed on the sex of Britney Spears' unborn baby. Astrologers and psychics alike all seem to put the odds on it being a boy, with the main reason being that she's "carrying high," and that she's been buying both boy and girl baby accoutrements to throw off the press (thus the "twins" rumor). One thing is for sure: Britney's pregnancy stylists must've lost their eyesight in a fire.
