Angelina Jolie will miss her aunt's funeral because it clashes with the premiere of Brad Pitt's new movie World War Z.

The Salt actress - who recently revealed she underwent a double mastectomy after she was identified as carrying the BRCA1 cancer gene - lost her aunt Debbie Martin, 61, over the weekend following a battle with breast cancer but Angelina cannot make the funeral in San Diego on Sunday because she will be in London.

"We are making the final arrangements for the funeral as we speak. But we expect it to be this Sunday at noon at El Camino Memorial in Sorrento Valley near our home. Angelina will be in London on Sunday so she won't be able to attend but she has been in touch with us and with various other members of the family, which has obviously been lovely and has meant a lot to us," Debbie's husband Ron told E! News.

Ron also revealed the family are hoping to start a charity to raise money for BRCA genetic testing: "We are currently in the process of setting up a foundation in Debbie's memory and we are hoping to raise money for women who can't afford to get BRCA testing. We are hoping to work with a charity called the Clearity Foundation so that every woman in America will have access to BRCA testing that could save her life--no matter how much money she has."
