Lizzo visits Library of Congress to play flutes in DC

Lizzo is slated to bring her "Special" tour to the Capital One Arena Tuesday, but before she hits the stage she made a stop at the Library of Congress on Monday. 

Over the weekend, the Librarian of Congress Carla Hayden invited the Grammy award-winning singer to visit the library and play "a couple" flutes. 

"The Library of Congress has the largest flute collection in the world with more than 1,800. It incl Pres James Madison’s 1813 crystal flute," Hayden tweeted Friday. "We would love for you to come see it and even play a couple when you are in DC next week. Like your song they are "Good as hell."

Lizzo surprisingly responded to Hayden on Saturday. "I'm coming Carla! And I'm playing that crystal flute!!!!!" she tweeted. 

Lizzo was spotted at the Library of Congress Monday afternoon. One library patron tweeted that Hayden "personally asked if it was okay" for Lizzo to play. The Library of Congress typically prohibits "making disruptive noises" and "using any musical instrument or other device for the production or reproduction of sound."
