On Monday night’s at-home edition of “The Tonight Show Starring Jimmy Fallon,” the host was joined by Lady Gaga, who asked Fallon if he’d like to be part of a special phone call.

“I don't know if he knows he's going to be on TV just yet, but we're going to FaceTime him and find out,” Gaga said, according to Daily Mail.

She then proceeded to FaceTime Apple CEO Tim Cook while turning the camera to face Fallon.

“So, Tim, I feel bad because you’re on TV,” Gaga said to a grinning Cook.

But the Apple CEO didn’t seem to mind and confirmed on the call that Apple would indeed be donating to support the United Nations’ COVID-19 Response Fund as part of Gaga’s new “One World: Together at Home” event, NPR reported.

The event aims to bring together a variety of singers, actors and other celebrities to “celebrate the courage of the human spirit.” Fallon will be one of the hosts along with fellow late-night comedians Stephen Colbert and Jimmy Kimmel.

So far, Gaga promises that Andrea Bocelli, Billie Eilish, Elton John, David Beckham, Idris Elba, J Balvin, Kerry Washington, Priyanka Chopra, Lizzo, Sir Paul McCartney and others have already signed on to participate. The event has already raised $35 million dollars, although, Gaga said that the goal during the airing will not be to raise money but simply to offer a sense of solace and community for those suffering around the world. She encourages people to “put away your wallets” and “just sit back and watch the show.”

“Number one, I want to highlight this global kind community that’s coming together right now,” Gaga said. “And it’s this valiant effort that we’re all witnessing, this triumph that is the medical community, it’s amazing what’s happening with them.”

AppleInsider reported Monday that Cook promised a $10 million donation to go toward the event. After Cook agreed to participate on the call, Gaga and Fallon both expressed gratitude.

“Tim, my next single’s called Tim Cook,” Gaga joked.

This isn’t the first time Cook and Gaga have crossed paths. In May 2019 Gaga performed a secret concert in at the opening of Apple Park in honor of the late Steve Jobs, Billboard reported.

Cook later tweeted at the “Stupid Love” singer himself.

One World: Together at Home airs April 18 at 8 p.m. ET.
