Is there anything Gwyneth Paltrow can't do? She's an Oscar winner, a mother of two and an expert at keeping one's intestine squeaky clean. Now, she can add yet another talent to her long list of accomplishments: benevolent bikini designer.

People magazine reports Gwyneth, who will soon debut her own clothing line, has created a limited-edition itty-bitty blue and pink two-piece for fashion retailer Lilly Pulitzer's A Colorful Cause: Celebrity Designer Program, which marks the company's 50 years of support for the Epidermolysis Bullosa Medical Research Foundation.

Other stars contributing to the charitable effort include Marcia Cross, Debra Messing, Brooke Shields and Bridget Moynahan, who are all designing matching styles for moms and their sure-to-be-resistant kids.

Also doing the do-gooder thing is Nicole Richie, who is auctioning off some of 14-month-old daughter Harlow's high-end accoutrements on handmedowns.com.

Among the stylish items that have been gently used (translation: they're spit-up and crusty-milk free) by the exceedingly adorable tot are a rainbow-striped cashmere sweater, a pair of moccasins and a luxe stroller signed by the starlet, who is expecting baby No. 2 with boyfriend Joel Madden.

Proceeds from the sale will go to the couple's Richie-Madden Foundation, which provides assistance and opportunities to disadvantaged kids.

"When I heard about this auction, I thought about how fortunate I am to be able to give Harlow so many things, from basic essentials to clothes," Richie writes on the foundation's MySpace page. "I have seen firsthand how many children lack the most basic items. I was so happy to clean out her closet and donate some of her hand-me-downs to this auction."

And in a final bit of do-gooder news, Madonna put aside her own recent troubles and reached out to victims of the powerful earthquake that hit Italy on Monday, leaving more than 250 people dead and tens of thousands homeless.

According to "Entertainment Tonight," the Big M "responded generously" to a request for her help made by the mayor of Pacentro, a village her grandparents once called home.

"I am happy to lend a helping hand to the town that my ancestors are from," Madonna tells People magazine, which puts her donation in the $500,000 range. "My heart goes out to the families that have lost loved ones or their homes."
