Surprise surprise, the next time you don your favorite pair of Jessica Simpson jeans, you could be helping a good cause. Multi-platinum singer, TV personality, designer, and philanthropist Jessica Simpson has just launched a new Facebook application, Show Me Your Blues, as a part of her initiative A Beautiful Me. Simpson is encouraging Facebook fans to upload a picture of themselves in their favorite jeans and each picture will raise money for charity. After filming VH1’s “The Price of Beauty“ and working with Operation Smile, a project that provides surgeries for children born with a cleft lips or palates, Simpson decided to launch A Beautiful Me in fall 2009. The initiative is an Operation Smile collaboration, and encourages young people to believe in themselves and their ability to change in the world. Simpson already has the support of her BFF Cacee Cobb, sister Ashlee Simpson Wentz and her rocker hubby Pete Wentz showing their blues. Now you can join the designer by merely uploading a pic of you in your Jessica Simpson jeans to the Facebook page, and join in as Jessica combines two passions, fashion and philanthropy, for the ultimate good reason.
