When Ariana Grande dropped new single "Focus" at the end of October, we got pumped for a horn-heavy, highly danceable album -- and then she said Moonlight actually sounded nothing like that.

But all is not lost. On Tuesday, enigmatic pop vocalist Who Is Fancy revealed that Ari will be singing on his next single, "Boys Like You." Ari confirmed it with an Instagram post of her own.

#BoysLikeYou @whoisfancy I love this song I love this song I love this song and I love you, Fancy. So excited for your bright shiny future and to be a part of this. Let em have it @whoisfancy !!!! ??

She showed a ton of love to both the song and the singer in the caption: "#BoysLikeYou @whoisfancy I love this song I love this song I love this song and I love you, Fancy. So excited for your bright shiny future and to be a part of this. Let em have it @whoisfancy !!!! ?"

And Wednesday, Who Is Fancy confirmed yet another guest on "Boys Like You" -- his former tourmate Meghan Trainor.

Surprise!!! I'm so thrilled to announce @meghan_trainor will also be featured on my new single #boyslikeyou! Meghan you've been my homie for so long!

This is cool for many, many reasons, but namely because Fancy's sound is fun and a little frisky (at least based on debut single "Goodbye," which dropped in February). But for real, who is Who Is Fancy? And did he choose his name perfectly to guide us down this rabbit hole of mystery and intrigue? Probably, yes. But here's what we know so far:

"Boys Like You" could drop this week.

Lettin y'all see a bit of the cover art for #boyslikeyou. So freakin excited to put new music out! Stay posted?❤️? pic.twitter.com/UKZHtcPQH0
