Christina Applegate is getting some help from her famous friends to raise awareness about breast cancer and Lee National Denim Day, one of the largest single day fundraisers for breast cancer in the country. Stars like Fergie, the cast of ABC’s Desperate Housewives, Ashley Tisdale and more have joined forces with the breast cancer survivor to autograph one-of-a-kind “I Love…” T-shirts to be auctioned off to benefit Christina’s foundation Right Action for Women. “I’m overwhelmed by so many familiar faces who have designed a T-shirt to help Right Action for Women, which is all about getting high-risk women screened appropriately for breast cancer.” Christina says in a statement. The actress is also serving as this year’s Lee National Denim Day ambassador, which benefits the Women’s Cancer Programs of the Entertainment Industry Foundation (EIF). The campaign encourages people to wear their jeans on Friday, October 2, in exchange for a $5 donation to support crucial breast cancer research. In anticipation of Denim Day, you can bid on the star-signed T-shirts from now until October 2 only at charityfolks.com to benefit Right Action for Women, or purchase Christina’s “I Love Life” T-shirt, $20, at denimday.com.
