– LONDON – Brad Pitt and Angelina Jolie stepped out together Sunday at the premiere of zombie thriller “World War Z” — Jolie’s first public appearance since announcing last month that she had undergone a double mastectomy.

The couple said they had been moved by the outpouring of public support that followed Jolie’s disclosure. Jolie told reporters she felt great, and had “been very happy to see the discussion about women’s health expanded” by her announcement.

“And after losing my mom to these issues, I’m very grateful for it,” she said.

Jolie revealed last month in an op-ed piece for The New York Times that she had the mastectomy after discovering she has an inherited genetic mutation that puts her at high risk of breast and ovarian cancer.

The 37-year-old actress revealed that, beginning in February, she underwent three surgeries — which she succeeded in keeping secret from the public — in which her breasts were removed and later replaced by implants. She said the procedures had reduced her chance of developing breast cancer from 87 percent to under 5 percent.

Pitt said, “The fact that she would not be frightened of this, what she would have to go through to do this, to take this specter away from our family and ensure that she would be there longer for our family, and the kids I get very emotional about it.”Actor to give up ‘Doctor Who’ roleLONDON – Who will be the new Who?
