Ariana Grande and Justin Bieber have already raised thousands of dollars for the battle against coronavirus with their new collaboration, Stuck With U, within hours of the song’s release on Friday morning. 

The singers, both 26, have pledged the proceeds from the song to the children of people working on the Covid-19 frontline.

The pair have sung duets together before, notably at last year’s Coachella music festival, and for Bieber's 2015 hit Sorry.

The music video for the new song features clips of people at home during the Covid-19 restrictions dancing - and lots of cute pets.

In the video, Bieber dances with his wife, while Grande dances with a mystery man in black. 

Speaking about the collaboration on Instagram, Grande said: "I can't fully articulate ……… howwwww happy i am that we waited this long to do this (the duet thing).

"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. Grateful to be doing this with my friend."
