Mulligan and Clooney at White House
Carey Mulligan, George Clooney, Damian Lewis and Hugh Bonneville were among the famous faces who attended a star-studded White House dinner during a visit by the British Prime Minister.
The actors - along with American Vogue editor Anna Wintour, The Wire's Idris Elba, Downton Abbey's Elizabeth McGovern and movie mogul Harvey Weinstein - were at the glitzy event held by US President Barack Obama and First Lady Michelle in honour of David Cameron and wife Samantha.
English folk-rock band Mumford & Sons - a favourite of Mrs Cameron - and US R&B star John Legend provided entertainment, while produce from the White House's own kitchen gardens was used in the winter harvest-themed meal.
Virgin boss Sir Richard Branson, Olympic gold medallist Denise Lewis and golf star Rory McIlroy were also on the guest list, along with politicians George Osborne and William Hague.
The US President praised the Camerons for their "strength" as parents as he toasted them at the dinner, held in a marquee on the South Lawn.
