So sweet!

Ariana Grande performed at her Manchester One Love concert on Sunday, June 4 in order to raise money to benefit all of the families who were affected by the suicide bombing that happened at her May 22 concert in the city — and her boyfriend Mac Miller was there not only to support her, but he also performed two duets with her!

“Tonight is all about love, am I right? Come on, let’s go,” Ari told the crowd before Mac came on stage.

The adorable couple sang her hit song “The Way,” followed by his hit song “Dang!”

Rumors about their duet first started swirling after Entertainment Tonight obtained a set list that revealed he was set to take the stage with his girlfriend toward the end of her three-hour concert.

He’s also been a big part of her support system after the terrorist attack, and he was the first to greet her as she got off the airplane from Manchester in Boca Raton, FL, ET reported. The two were photographed as Mac gave her a big hug — and it seemed like Ari really needed to be comforted after the ordeal she went through with her fans.

“Ariana isn’t doing well at all,” an insider previously revealed to Life & Style. “She feels responsible and can’t shake the sound of the bomb. But the screams are what make her incredibly emotional. She can’t stop thinking about them.”
