Angelina Jolie made her first public appearance Sunday at the World War Z premiere in London, after announcing, May 14, she had a preventative double mastectomy earlier this year.

The actress wore a floor-length Saint Laurent gown, in her signature black with a sheer cut-out at her belly.

Jolie's appearance eclipsed the star of the show, Brad, who co-produced and stars in the zombie thriller. In the film, Pitt plays a United Nations employee battling to save the world from a zombie apocalypse.

The pair signed autographs for fans in Leicester Square, while rock band Muse (with frontman Matt Belemy, Kate Hudson's baby daddy) provided the tunes.

Angelina told multiple news outlets she "feels wonderful" and that she's "grateful for all the support."
