The White House Correspondents' Dinner went down last night in D.C. -- and it was packed with celebs ranging from Reese Witherspoon to Kim Kardashian.
Reese lead the baby bump train while wearing a black dress to the event ... and was followed by Anna Paquin, who showed off her growing belly in a sexy cut-out dress.
Rosario Dawson showed off some different lady lumps, as she stepped out in a very revealing green gown that put her cleavage on full display.
Also spotted at the event: George Clooney, Lindsay Lohan, Charlize Theron, "Hunger Games" star Josh Hutcherson, "Modern Family" stars Sofia Vergara, Eric Stonestreet, Julie Bowen and Jesse Tyler Ferguson, Kate Hudson, Zooey Deschanel and many more.
