Behind the Scenes at White House Correspondents' Dinner

Kerry Washington, Helen Mirren and Kendall Jenner were all there.

Mirren, 70, honored Prince by showing off a new purple "tattoo," featuring the symbol the late singer used as his moniker at one point during his career. Prince died last month at the age of 57.

Across the dinner, Kendall Jenner was seen posing with two other attendees.
