The LEGO Movie may have been snubbed in the Best Animated Feature Film category at the Oscars last night, but that didn’t stop Tegan and Sara and The Lonely Island from taking the stage to perform the movie’s hit song “Everything is Awesome”.

Everything got really awesome about halfway through the performance when Will Arnett, voice of LEGO Batman, appeared in Val Kilmer’s Batman costume to sing part of his Batman song. The Batsuit’s emblem was made up entirely of LEGO.

Will Arnett will star in his very own LEGO Batman movie in 2017.

Check out the Oscar performance that everyone is talking about in the video above!
