Following the 24-year-old Grande's performance at the KIIS-FM Wango Tango show in Los Angeles Saturday, Davidson posted a still image from the show on Instagram Stories, captioned "Are you [expletive] kidding me!??" He shared Instagram photos of the two in their best Hogwarts couture, glimpses of her sock-covered feet in videos and messages about how "f**king lit" she is in Instagram Stories of her performances.
The mask looks strikingly similar to the mask Grande occasionally wears on stage and certainly the mask she wore on the cover of her latest album, Dangerous Woman.
Reese captioned the black-and-white snap, "We had a good night".
While Davidson didn't directly reference the "No Tears Left to Cry" singer in his set - even though PEOPLE confirms that Grande showed up to support her new beau - the comedian did appear to be wearing one of her sweatshirts onstage. "Pete loves him some Ariana".
Buzz about Grande and Davidson dating began bubbling up at the end of May, just a short period after she broke up with ex-boyfriend Mac Miller. "Everybody is different and there are a lot of treatments for mental illnesses and I have done/am doing all of them", he continued. Davidson, who is a member of the Saturday Night Live cast, has been absolutely smitten with Grande. In her first Instagram post since Grande and Davidson's relationship was revealed, David wrote: "Been in Africa, what'd I miss??"
