Ariana Grande and Mac Miller are going very public with their relationship -- sucking down sushi and each other's faces, and we got the pics.
The couple hit up Katsu-Ya in Encino Sunday night and couldn't keep their hands off of each other -- kissing and giggling through the meal. Witnesses tell us at one point Ariana was even lying on his lap.
Sources close to them tell us they are dating, even though Mac's downplayed their relationship in interviews ... referring to Ariana as just a "homey."
They've got some history. Before Ariana hooked up with Big Sean ... Mac was on the scene as her boyfriend in her "The Way" music video.
Way to go, homey.
She doesn't need a "publicity stunt" please and even less with Mac Miller... like she can do way better.
The Selena/Taylor stans running in here to talk about PR relationships nnnnnnnnnn
Yikes I'm most definitely not a Selena stan thank you very much, also I'm not a Taylor stan anymore, I just don't think ATRL+ is worth it so that's why I'm keeping my name but nice try
