Now we know at least one guest expected at the Wednesday night state dinner for U.K. Prime Minister David Cameron: Actor Damian Lewis, star of “Homeland,” the counter-terror drama that’s a favorite of President Obama’s. Lewis, a British thespian who plays a former American POW, leaked news of his White House invitation during an appearance last week on the BBC’s “Graham Norton Show.” “It’s just the Obamas, the Lewises and the Camerons in the kitchen,” he joked. But seriously: “It will just be a thousand of [the president’s] closest friends, but I don’t care.” By the way, George Clooney is in town that same day to celebvocate about Sudan before a Senate committee — maybe someone’s rustled up a dinner ticket for him? His rep did not get back to us.
