Actress Kate Mara has joined the celebrity vegan club after giving up her love for cheese.

The House of Cards and Shooter star admits her family and friends aren't that surprised by her healthy diet, but they are shocked she was able to stop eating cheese.

She explains, "I'm a vegan, but that doesn't mean I get up and leave if I'm out to dinner with someone who orders steak.

"Their biggest surprise is that I don't eat cheese anymore, and I don't blame them because cheese was definitely the hardest thing to give up."
