Washington, D.C. was the most popular place to be this weekend! Some of the biggest names in Hollywood jetted to the nation’s capital to catch a glimpse of President Obama for the 98th Annual White House Correspondents’ Dinner, and the oodles of cocktail parties that came along with it. After garnering plenty of laughs as host of the event—where Reese Witherspoon (in Monique Lhuillier) mingled with New York Senator Kirsten Gillibrand—comedian Jimmy Kimmel ventured over to the French Ambassador’s house for the Bloomberg andVanity Fair reception, along with Sofia Vergara (in David Meister), Kate Hudson (in Jenny Packham), George Clooney, and Kerry Washington (in Calvin Klein). “I thought the POTUS [President of the United States] was hilarious,” Tweeted Washington. “It was a wonderful weekend.” See more stars at the weekend’s hottest events—D.C. and beyond—in the gallery.
