Imagine all the people, indeed.

"Wonder Woman" star Gal Gadot enlisted the help of a myriad of famous faces to sing John Lennon's "Imagine" as a way to boost morale amid coronavirus quarantines in the U.S. and around the world. Stars like Will Ferrell, Natalie Portman, Jimmy Fallon, Zoe Kravitz, Amy Adams, Mark Ruffalo, James Marsden, Sarah Silverman, Maya Rudolph and more sent in their own selfie videos.

"Day six in self quarantine, and I've got to say these past few days got me feeling a bit philosophical," Gadot said in the video posted to her Instagram account Wednesday night. "This virus has affected the entire world. Everyone. Doesn't matter who you are, where you're from. We're all in this together."

Gadot said she was inspired by a video of a man in Italy playing the trumpet from his balcony for the other tenants in his building.

"He was playing 'Imagine' and there was something so powerful and pure about this video. And it goes like this," she said, before singing the first line of the song. The video then cut to various celebrities singing a line each.

"We are in this together, we will get through it together," Gadot captioned the post. "Let’s imagine together. Sing with us ❤ All love to you, from me and my dear friends."

JoJo used her downtime while self-quarantining to remix her hit 2004 single, "Leave (Get Out)," with lyrics relating to the global coronavirus pandemic and social distancing.

She named the new coronavirus remix: "Chill (Stay In)."

In a TikTok video, JoJo sings to the tune of her single: "Tell me why you’re acting so confused, when the CDC laid it out for you. Come on, I know you’re not dumb. To go behind my back and hit the bar, shows how immature you really are. Keep exposure to a minimum!"

"Stay in! Right now! Do it for humanity. I'm (expletive) about that, but we will survive," she concluded.

Jojo, Gadot and co. join a growing list of celebrities who are continuing to entertain fans from home, even as movies, television shows, concerts and other forms of entertainment get shut down to minimize the spread of coronavirus.

Even without their formal talk show formats, hosts like Fallon, Jimmy Kimmel, Ellen DeGeneres and Samantha Bee have continued with informal shows online. And musicians including John Legend, Chris Martin of Coldplay and Keith Urban are performing live mini-concerts from their homes on Instagram to keep fans entertained even thought they can't attend real shows.
