Ariana Grande is reportedly dating Social House band member Mikey Foster 10 months after splitting with fiancé Pete Davidson. But who exactly is this mystery man? Foster is currently on tour with Grande and his group Social House, and just released a new song with the singer, the subtly titled “Boyfriend.”

In the music video for the song, Foster and Grande play lovers, making out for the whole world to see. Back in December, Grande teased the possibility of a collaboration with the musical duo.

“I don’t want to do what people tell me to do, I don’t want to conform to the pop star agenda. I want to do it on my own terms from now on,” she said. “If I want to tour two albums at once, I’m going to tour two albums at once. If I want to drop a third album while I’m on tour [in 2019], I’ll do that too! Please. Social House is my opening act—you don’t think we’re going to have a studio on the bus? That we’re not going to be making records on the road? Of course we are.”

Foster has previously worked with Grande, helping her with her chart-topping singles “Thank U, Next” and “7 Rings.” According to The Blast, Grande and Foster have been seeing each other for a while, but are taking things slow and “just feeling things out.” They aren’t being totally private, though, and were recently photographed walking arm-in-arm.

Foster also wished a very sentimental happy birthday to Grande back in June writing, “Ur one of the most incredible people the universe has to offer. I hope this year offers u nothing but the joy u deserve. Love u. happy birthday.”

Grande commented on the photo, a snapshot of her as a baby, writing: “love u sooooooo much.”
