Rivers Cuomo of musical guest Weezer performs on 'The Tonight Show Starring Jimmy Fallon' on March 31, 2016.

Earlier this year, Weezer announced its tenth studio album -- its own “White Album,” unofficially -- would hit stores on April 1. All that proved to be no April Fools' joke, but the long-running rock band still goofed around during its visit to The Tonight Show Starring Jimmy Fallon yesterday (March 31). 

Frontman Rivers Cuomo came out dressed in an all-white, chest hair-revealing Elvis costume to perform new song “King of the World” alongside his normally dressed bandmates. 

Check it out below:

“King of the World” was one of numerous tracks off the album -- including “Thank God For Girls” and “Do You Wanna Get High?” -- which Weezer revealed ahead of today’s release date. The self-titled record dropped today via Crush Music and Atlantic Records. It follows blue, green and red in the lineage of self-titled Weezer albums colloquially named after the color of their cover art.
