The actress sizzled in an all-white Ralph & Russo ensemble, including a strapless peplum top with a metallic accent around the waist. She also wore white pumps, drop earrings and a gemstone bracelet.
The German premiere was the star's third public appearance since announcing last month that she had undergone a double mastectomy. On Sunday and Monday, she joined Pitt at the London and Paris premieres of his zombie film.
On the eve of her birthday, Pitt treated Jolie to an intimate dinner at high-end wine restaurant Il Vino in Paris.
The actor has spoken up about Jolie's bravery, telling reporters over the weekend: "I'm very proud and just relieved that's (breast cancer) not going to be the thing that takes her out. The biggest fear as a father is keeping the family alive, safe and together - she did that. I'm getting a bit teary-eyed thinking about it... It is heroic."
The couple have six children together.
