The 'Sorry' hitmaker - who is married to Hailey Baldwin - was spotted with the 17-year-old artist during the 'No Tears Left to Cry' hitmaker's performance last Sunday.
In the video, the two can be seen looking at each other as the crowd roars behind them, before a long hug. The singer, who wore a white mask, shared the video on his Twitter account and wrote, "Great show @ArianaGrande. I am very proud of you! @billieeilish." Justin also posted a picture on his Instagram Story of the two stars meeting: "So that's what happened. You have a great future ahead of you." The 'Bury Your Friend' hitmaker was also able to meet Justin's wife Hailey and the trio even danced with 'Late Show' host James Corden.
Recently speaking to 'Entertainment Tonight', Billie revealed that Justin wrote to her on Instagram and she even revealed that the two might be working together soon. The 'Bad Guy' singer - who is a 'Belieber' herself - didn't reveal exactly what the 'What Do You Mean?' hitmaker said, but opened up about the old messages Justin sent her in 2014 as herself "Image" was only twelve years old. She added: "When you follow someone you can see everything they've sent you in the past. It felt good and bad at the same time. The newcomer also revealed that she used to have a "huge" poster of Justin on her wall, praising him: "He's awesome. He is so cute. I really feel for him - he's been through a lot."
