Though she’s in the process of getting ready to launch her own line of clothing for charity, Gwyneth Paltrow has decided to take on some additional charitable design challenges as well. The actress has designed a limited-edition bikini for Lilly Pulitzer’s A Colorful Cause: Celebrity Designer Program, which honors the label’s 50th anniversary by supporting The Epidermolysis Bullosa Medical Research Foundation.

Joining Paltrow in the designing are five additional famous faces: Brooke Shields, Debra Messing, Marcia Cross, Angie Harmon, Bridget Moynahan, Catherine Bell, Elisabeth Hasselbeck and Garcelle Beauvais-Nilson have all signed on to lend their personal touches to the mommy-and-me creations. The clothes will be available for purchase in April at Lilly Pulitzer stores across the country and online at the official site.

Is it that time of year already?! Last holiday season, after Josh Lucas purchased a fake Christmas tree, Ecorazzi posed the question: Is an “organic” fake Christmas tree better for the environment than a real Christmas tree? Overall, most people had never heard of said “organic fake tree” and argued that a real tree is not only biodegradable but grown to be chopped down, thus making the latter option far more environmentally friendly. Well, as the holidays approach, the Christmas tree is once again being foisted into the spotlight, but this time for charity.

Actors Julianne Moore, Brooke Shields, Angie Harmon, Eva Longoria Parker and Tony Parker have personally designed Christmas trees – with the help of Robert Verdi and Smith & Hawken — for an online auction to benefit Keep America Beautiful.

Keep America Beautiful “combines education with hands-on stewardship to make America’s communities cleaner, greener, safer, and more livable.” Matthew M. McKenna, President and CEO of Keep America Beautiful said, “This is such a great concept for a fundraiser, and with the A-list stars supporting it, Keep America Beautiful couldn’t be more thrilled to be the chosen beneficiary. The funds generated by this auction will help us in fulfilling our grassroots mission to build cleaner, greener, stronger communities nationwide.”

To participate in the auction, simply visit SmithandHawken.com/Trees between October 15 and December 5th and click on the “BID NOW” button. The auction winners will receive their special trees just in time for the holidays. Happy bidding!

The campaign, stemming from the CJ Foundation for SIDS, is featuring strollers (donated by Maclaren) designed by Tori Spelling, Ashley Simpson, Angie Harmon and Marissa Jaret Winokur that will be auctioned off by Charity Folks to promote SIDS Awareness Month and raise some funds for the CJ Foundation. Celebs getting artsy again for a good cause… I love it.

The auction will run October 6 through 13, and you can also catch the designs on display at Babies”R” Us in New York City’s Union Square.
