George Clooney, Jennifer Lopez and Lindsay Lohan will be joining a host of other celebrities in Washington DC to celebrate Barack Obama's inauguration later today.
The Ocean's Eleven star was the first star to touch down in the capital
The Mean Girls actress joined Jessica Alba, Hayden Panettiere, and Jamie Foxx to kick-off the inauguration celebrations at the Declare Yourself event on Sunday, which saw performances from John Legend and Maroon 5.
Samantha Ronson was also there to keep the party going on the decks.
The Jonas Brothers, Demi Lovato and Miley Cyrus were all lucky enough to perform at the inaugural concert for kids last night - and no doubt put a smile on Malia and Sasha Obama's faces.
And Oprah Winfrey has brought her show to Washington DC for the Inauguration, with guest stars Demi Moore and Ashton Kutcher.
Other stars to have descended on the US capital include Jennifer Lopez, Ben Affleck, Courtney Cox and Jay Z.
