Angelina Jolie made her first appearance since revealing she underwent a double mastectomy when she walked the red carpet at the London premiere of Brad Pitt's new movie World War Z on June 2.

“It really shows you that one person can make a difference," Brad told Extra at the event. "I was incredibly proud of her way before this, but it's a very brave decision.”

Brad also said the couple made sure their children knew exactly what was going on with mom. “We have a policy in our family, no secrets… I mean there's an age of understanding, so you've got to present it in a way that is age appropriate, but we know our children very well… we want everything to be on the table and any questions they have for them to ask.”
