Brad Pitt had fiancée Angelina Jolie, who wore a black Saint Laurent gown, on his arm to premiere World War Z in London yesterday. He also had the support of his sons, Maddox and Pax, at the event. The premiere marks Angelina's first public appearance since announcing the news that she underwent surgery for a preventative double mastectomy last month. She stayed close to Brad for the red carpet festivities, which also brought out Matthew Bellamy and his Muse bandmates. Brad has been busy promoting the film leading up to its June 20 release, and on Saturday he made a surprise appearance at a World War Z screening in London. Brad and Angelina are not the only stars currently in the UK since Saturday night's Chime For Change benefit concert had Beyoncé Knowles, Jay-Z, Blake Lively, Jennifer Lopez and more sharing the stage at London's Twickenham Stadium.
Angelina stepped out in support of Brad on the heels of a sad occasion since her aunt Debbie Martin passed away after a battle with breast cancer last week. Angelina is still in the midst of preventative measures as she announced that she plans to have her ovaries removed as well due to the BRCA gene, which increases her risk of breast and ovarian cancer.
