The pop stars last teamed up for a performance during Ariana's headline set at Coachella last year.
They duetted on Justin's 2015 hit 'Sorry' for what marked Justin's first live performance in two years.
Meanwhile, the pair also recently joined Billie Eilish in launching a set of cloth face masks to raise money for musicians affected by coronavirus.
The trio are just some of the stars who have designed their own face masks to support the charity Helping Musicians UK.
Alongside the products, they wrote: ''100 per cent of the net proceeds from the sale of this product will be donated to the musicians benevolent fund, working as Help Musicians UK, with a minimum donation per product sold of £8/€8/$8 ... Helping Musicians UK is an independent UK charity for professional musicians of all genres, from starting out through to retirement.''
