She chooses the products/foundations she will endorse very carefully, and now Jennifer Aniston has agreed to be the ambassador for the 2013 Key to the Cure campaign.

The stunning Hollywood actress was announced as the face of the cancer research fund earlier this week by Saks Fifth Avenue and the Entertainment Industry Foundation and will take part in a PSA later this year.

Speaking about the opportunity, Jennifer says, "I'm so honored to join the Entertainment Industry Foundation and Saks Fifth Avenue in their continued efforts to raise funds for promising scientific research through EIF's Women's Cancer Research Fund," adding, "My hope is that everyone will contribute to this worthy cause by purchasing a Key To The Cure T-shirt designed by Emilio Pucci."

The shirt, which was designed by Peter Dundas of Emilio Pucci, will retail for a reasonable $35 and will be available at Saks stores nationwide starting Oct. 1st.
