Helen McCrory has confessed she pinched a napkin from The White House as a souvenir.
The Harry Potter star - who will appear in the new James Bond film - attended a dinner with President Barack Obama with her husband Damian Lewis, star of hit US show Homeland.
Helen said: "I didn't nick anything but I did take home a napkin with the White House crest on it as a souvenir."
She added: "We looked at the table plan and found we were on table number ten, the same as the Obamas, David and Samantha Cameron and Warren Buffett. It was really quite nerve-racking.
"My husband's show Homeland is Obama's favourite so all the staff wanted to talk to him because they wanted to talk to the guy that their boss likes.
"So we were having these extraordinary conversations with people who run the most powerful country in the world about what their new policies are going to be, really fascinating conversations."
