Angelina Jolie was all smiles at the London premiere of partner Brad Pitt's latest film World War Z - the first public apperance the starlet has made since writing about her double mastectomy surgery last month. The 37 year-old mother of six - who underwent the surgery after discovering she had a mutated gene which predisposed her to cancer - looked radiant in a simple black dress, quelling any concerns of her recovery.

Due to having to attend the movie premiere, Jolie was unable to attend the funeral of her aunt, Debbie Martin, who recently lost her battle with cancer.
