If President Obama didn't have enough big names at his last dinner honoring South Korea in October, he sure is making up for it as he honors British Prime Minister David Cameron on Wednesday night.
Actors George Clooney and Damien Lewis (the star of one of Obama's favorite shows, "Homeland") are expected to attend the black-tie dinner. They will be alongside singer John Legend, movie studio boss Harvey Weinstein, Richard Branson and billionaire Warren Buffett (minus his much publicized secretary.)
Lots of lawmakers in the house, too: Sens. John Kerry (D-Mass.), Claire McCaskill (D-Mo.) and Chuck Schumer (D-N.Y.), along with Maryland Gov. Martin O'Malley.
Mumford and Sons will perform at the dinner, which will also be attended by Carey Mulligan, Idris Elba of "The Wire" (another of Obama's favorite shows) and Hugh Bonneville of "Downton Abbey."
