Lin-Manuel went to the BAFTAs tonight and seemed to be having a fantastic time.
But one of the highlights of his night seemed to be when he got a picture with J.K. Rowling.
The best part about the whole picture is that Lin-Manuel captioned the picture with a Harry Potter quote.
J.K. Rowling wasn't the only person Lin-Manuel had a fanboy moment over. He also met Pixar legend John Lasseter.
Looks like Lin-Manuel had a great night!
