Lil Dicky used to be the underdog comedy rapper.

He's come a long way from that.

Today, Dicky jumped on Instagram and teased a new project called "Earth". It is believed to be a song and a video but is dropping tomorrow during the traditional album release slot of Thursday at midnight

Whatever it is, it features a good chunk of the celebrities on the planet, including Justin Beiber, Ariana Grande, Halsey, Zac Brown, Miley Cyrus, Wiz Khalifa, Snoop Dogg, Kevin Hart, Adam Levine, Shawn Mendes, Charlie Puth, Sia, Hailee Steinfeld, Lil Jon, Rita Ora, Miguel, Katy Perry, Lil Yachty, Ed Sheeran, Leonardo DiCaprio, Meghan Trainor, Joel Embiid, Tory Lanez, John Legend, Bad Bunny, Psy and The Backstreet Boys.

Check the trailer.

Dicky (and Chris Brown) struck viral gold with "Freaky Friday". Can the prankster do it again?
