Two of music’s biggest stars are teaming up for a good cause.

Ariana Grande and Justin Bieber join forces on their highly-anticipated duet “Stuck With U.” The two embrace the times and serenade their significant others on the tender ballad. “Got all this time on our hands / Might as well cancel our plans / I could stay here for a lifetime,” sings Ariana, while Bieber responds, “And there’s nothing I can do / I’m stuck with you.”

All proceeds from the song will benefit the First Responders Children’s Foundation, which provides grants and scholarships for children of health care workers, EMTs, paramedics, police officers, and firefighters on the front lines of the COVID pandemic.

The video was shot amid the quarantine and features at-home cameos from celebrities including Jaden Smith, Chance the Rapper, Steph and Ayesha Curry, Kendall and Kylie Jenner, and Gwyneth Paltrow. Bieber’s wife Hailey and Ariana’s new boyfriend, real estate agent Dalton Gomez, also make cameos.

Taking to Instagram, Ariana reflected on the long-awaited collaboration. “i can’t fully articulate ……… howwwww happy i am that we waited this long to do this (the duet thing),” she said. “this moment really means so much more than it ever could have if it had happened any other way or if it had been any other song. being able to lend our voices to this project and collaborating on this has been so fulfilling and i really just love this song so much.”

Justin and Ariana previously collaborated on a remix to Bieber’s 2015 hit “What Do You Mean?” and performed together at Coachella last year. They also share the same manager, Scooter Braun. “We wanted to show our gratitude to the men and women on the front lines who work tirelessly for our health and safety during this crisis,” said Braun. “They are the everyday heroes and now more than ever they and their families deserve our support.”
