It should have been Brad Pitt’s night to shine, but at the world premiere of his film World War Z in London Sunday night, all eyes were on his fiance, Angelina Jolie. Yes, she looked stunning in a black, floor-length Saint Laurent gown, but her red carpet arrival was more buzzed about due to the fact that it was the actress’s first public appearance since announcing that she had undergone a double mastectomy. Jolie made the preventative decision after discovering she carried the BRCA1 gene, which put her at risk for breast and ovarian cancer. (Jolie’s aunt, Debbie Martin, recently passed away from breast cancer, and her mother, Marcheline Bertrand, died of ovarian cancer in 2007.) Angie, we’re grateful to have you back on the red carpet, looking as gorgeous and healthy as ever.  Click to see photos of Angelina Jolie from every angle at the premiere.
