WATCH: Ariana Grande and Mac Miller Show Off Their Chemistry in ‘My Favorite Part’ Music Video

Ariana Grande and boyfriend Mac Miller pack on the PDA in “My Favorite Part” music video.

The real-life couple star as neighbors who become infatuated with one another after they meet on a rainy night. Not only is the chemistry between them undeniable, but the two fall in love through the walls of their apartments.

After serenading each other for nearly the entire video, he shows up at her door where she immediately  grabs his tattooed neck and pulls him inside.

“I love you @larryfisherman,” Grande wrote on an Instagram post announcing the video. “We made another cool duet and I like your singing voice.”

The couple previously worked together on Grande’s “The Way” in 2013.
