On Wednesday, the pop star dropped a teaser for his upcoming collaboration with comedian and rapper Lil Dicky titled simply, "Earth," which is arriving Thursday, at 9 p.m. PST.
But there's some other artists involved that you may have heard of including Ariana Grande, Miley Cyrus, Halsey, Snoop Dogg, Rita Ora, Katy Perry, Zac Brown, Brendon Urie, Wiz Khalifa, Shawn Mendes, Charlie Puth, Hailey Steinfeld, Ed Sheeran, Adam Levine, Sia, John Legend, Backstreet Boys, Kevin Hart. Miguel, Lil Yachty, Meghan Trainor, Tory Lanez, John Legend, Bad Bunny, PSY, Kris Wy, Benny Blanco, Leonardo DiCaprio and more!
The clip, which showcases the massive lineup, ends with Lil Dicky looking cautiously down a street before fading to black.
"Let's save the Earth @lildickygram," Bieber captioned the seductive clip. "New song and video tomorrow night."
On Monday, the 31-year-old rapper first broke the news that he and Bieber were working on something. He posted a video in which he told the camera directly: "Hi. I think I have to start talking to you guys about this new song and video I'm putting out this week because I'm so excited," Lil Dicky started off in his Instagram caption. "I've really never been this excited for anything in my life. There's so many things I want to tell you but I just want to start with two simple words: Justin Bieber."
He soon followed that up with another clip teasing Sia and DiCaprio's involvement.
Lil Dicky, known for melding his hip-hop skills and comedic chops (not to mention his knack for wrangling incredibly famous pals), appears to be crafting a follow-up to his 2018 track and music video, "Freaky Friday."
Judging by the title, DiCaprio's passion for environmentalism and Bieber's comment, it's a safe bet that the new track and video will find a comedic edge on saving Mother Earth.
