Ariana Grande and Justin Bieber have teamed up for a new song, with the proceeds going to a charity that raises money for the children of first responders in the US.

The pair will release the single Stuck With U on May 8.

Both stars announced the news via social media, sharing the single's cover art which features a drawing by cartoonist Liana Finck of two people sharing a house together. 

"Proceeds from sales and streams of Stuck With U will fund grants and scholarships for children of first responders who have been impacted by Covid-19," Bieber said.

Grande said she feels "grateful" to team up with Bieber to help the First Responders Children Foundation.

Grande then posted an instrumental piece of music from the song to her Instagram account, calling on fans to send videos of them dancing to it.

"Please use this instrumental & send us videos of u being your beautiful selves, dancing with your loved ones, pets, whatever / whoever brings u comfort during this quarantine (even if it's just u alone. that’s beautiful too.)," she said.
