Mac Miller is prepping for the release of his album The Divine Feminine, and it appears one of the guest appearances on the project is more than just a friend. Photos obtained by TMZ show Mac Miller and Ariana Grande sharing a kiss and other public displays of affection during a dinner at a sushi restaurant in California.

The two first worked together on Grande’s 2013 song “The Way,” but Miller consistently maintained in interviews that the two were just friends. Apparently, friends you kiss on the lips. I guess it worked for Lil Wayne and Birdman, right? Mac also appears in a series of photos from a choreography session posted to Ariana Grande's Instagram. 

Ariana Grande has a history with rappers, previously dating Big Sean. Miller’s musical output has been up ever since he quit using lean, and his new record looks to be shaping up nicely, with a single "We" featuring Cee Lo Green and a tracklist that features Anderson .Paak, Kendrick Lamar, and Ty Dolla $ign (among others).
