Naya River, Laverne Cox, Lucy Liu and Sophia Bush Stun at White House Correspondents’ Dinner 2015

The 101st annual White House Correspondents’ Dinner 2015 was last night and celebrities stunned on the red carpet (and on Instagram!).

Naya Rivera showed off her baby bump in a gorgeous white gown, while Sophia Bush put on a brave face in the wake of her ex-boyfriend Dan Fredinburg’s tragic passing in a Mt. Everest avalanche during the Nepal earthquake yesterday.

SNL’s Cecily Strong hosted the evening, and President Obama cracked jokes while his surprise guest Keegan-Michael Key of Comedy Central’s “Key and Peele” played the part of Luther, his anger translator, and spoke the truth.
