Say hello to pop music's cutest new power couple, Velcro and Baabyyy.

Ariana Grande and Mac Miller haven't kept their blossoming romance much of a secret since they were spied getting smoochy on an August 21 sushi date: In addition to Snapchat cameos, they enjoyed a public outing together at the 2016 MTV VMAs (Ariana walked the carpet alone but the two sat together at the show). And now Mac and Ari have made things Instagram official, right as they've also announced their newest collaboration.

"My Velcro," the "Dang!" rapper wrote on Instagram on September 8, captioning a photo of himself in the studio with Ariana wrapped tightly around him (Jezebel once documented Ariana's historical distaste for touching the ground with her feet). The picture appears to have been taken at a studio, and the pair have certainly logged some time in one recently: In addition to throwing a verse on a remix of Ariana's "Into You," Miller announced an upcoming collaboration with the pop star on his The Divine Feminine album. The song is titled "My Favorite Part," and the promo art is a split of the two gazing into each other's eyes. According to Mac's post, the song will debut at midnight ("9:00 PM PST").

Grande shared another photo of the two on Wednesday, in which Mac tackles Ariana on the ground as she wraps her legs around him. The "baabyy" she captioned it with is presumably NOT a "Baby I" reference, but the song's in my head now regardless.

"My Favorite Part" is Mac and Ariana's third collaboration counting their "Into You" remix; the rapper guested on her debut lead single "The Way" in 2013.
