Hollywood headed to the capitol over the weekend to attend the annual White House Correspondents’ Dinner in Washington D.C. The star-studded evening, attended by A-listers like Katy Perry (in Giambattista  Valli), Sofia Vergara (in Herve L. Leroux), Nashville stars Connie Britton (in Temperley London) and Hayden Panettiere (in Katherine Kidd), Jessica Paré (in Antonio Berardi), and Gabby Douglas (in David Meister), was filled with laughs courtesy of the night’s host Conan O’Brien and President Obama, who poked fun at himself and O’Brien in his humorous speech. “I understand that when the Correspondents’ Association was considering Conan for this gig, they were faced with that age-old dilemma: Do you offer it to him now, or wait for five years and then give it to Jimmy Fallon?” the President ribbed (watch his speech here).
