Angelina Jolie made her first public appearance, after revealing the news about her undergoing double mastectomy last month, at her fiance Brad Pitt's zombie thriller 'World War Z.'
Jolie even thanked the world for her support, saying that it meant the world for her, the Mirror reported.
The 37-year-old actress was accompanied by Pitt but had to miss her aunt's funeral, as it was on the same day.
