Check out the heartwarming -- and hilarious -- original tune.
How many superstars can you fit on a stage?!
Jimmy Kimmel recruited a few of his famous pals to help raise awareness and money for AIDS during a special episode of Jimmy Kimmel Live! on Tuesday night, partnering with Bono's charity RED. The Killers frontman Brandon Flowers, Channing Tatum, Julia Roberts, Kristen Bell, Neil Patrick Harris, Halsey and DJ Khaled all participated in a cute sing-along urging people to donate to the cause.
World AIDS Day is on Dec. 1.

"Oh baby, it's blowing, but our pockets keep growing," Bell sings at one point, joking about their wealth, "but if we don't help people with AIDS, we're going to hell."
Highlights of the song and dance number include Tatum and Harris showing off their tap dancing skills, and a surprise interlude from Bono himself, who's hilariously dressed like the devil.
The episode kicked off the second annual RED Shopathon, featuring limited edition (RED) products for sale, as well as a few pretty incredible experiences with celebrities via Omaze that you can enter to win by donating $10. Some experiences include partying with Tatum in Las Vegas at the premiere of his Magic Mike Live show, a private U2 rehearsal show, and a tea date with Roberts and Bono.
The A-listers, of course, aren't the only ones doing their part to fight AIDS worldwide. In July, Prince Harry honored his late mother, Princess Diana, in a moving speech for AIDS awareness at the International AIDS Conference in Durban, South Africa.
"When my mother held the hand of a man dying of AIDS in an East London hospital, no one would have imagined that just over a quarter of a century later, treatment would exist that could see HIV-positive people live full, healthy, loving lives," Harry said. "But we now face a new risk, the risk of complacency. As people with HIV live longer, AIDS is a topic that has drifted from the headlines. And with that drift of attention, we risk a real drift of funding and of action to beat the virus."
