Ariana Grande and Justin Bieber teamed up for a charity single to benefit the children amidst Covid-19 crisis

Ariana Grande and Justin Bieber have teamed up for a charity single to benefit the children of first responders amid the coronavirus pandemic.

The 26-year-old singers, who share manager Scooter Braun, announced this Friday that their song Stuck With U will be released on May 8.

Justin hinted there might be audience participation in the song, writing on Instagram: 'Check back later today for the instrumental so you can be a part of this.'

Both Ariana and Justin fired up their Instagram pages that morning and posted the single art by cartoonist Liana Finck who is often featured in New Yorker.

The art is of a stick figure house with two sparsely sketched people sitting on the floor inside, holding each other's hands.

'Working with our family at @sb_projects and universal music group proceeds from the sales and streams of #StuckwithU will fund grants and scholarships for children of first responders who have been impacted by COVID-19 in partnership with the First Responders Children’s Foundation,' he wrote.

Both he and Ariana teased a collaboration on Twitter the previous day, setting speculation swirling about whether they were making music together.

'Special announcement tomorrow at 10 am pst ...,' wrote Justin in a tweet Ariana quoted, writing: 'see u there everybody.'

Stuck With U will be the first recording Justin and Ariana release together but the pop stars have worked together before.
