Angelina Jolie -- First Appearance Since Mastectomy Announcement

In her first red carpet appearance since announcing she underwent a double mastectomy, Angelina Jolie posed for pics with Brad Pitt today at the London premiere of his movie "World War Z."

In an op-ed piece for the New York Times last month, Jolie revealed she underwent a preventative double mastectomy back in February because "doctors estimated that I had an 87 percent risk of breast cancer and a 50 percent risk of ovarian cancer."

Since making the announcement, Jolie has been recovering at home in Los Angeles before taking on her next project -- directing a film called "Unbroken."
