Pete Davidson Jokes About Being 'Very High' After Ex Reacts to His Romance with Ariana Grande

Pete Davidson prepared for his stand-up comedy set on Friday night by getting “very high.”

Before the 24-year-old comedian performed onstage at the Borgota hotel in Atlantic City, where he opened for Dave Chappelle in a special event celebrating the hotel’s 15th birthday, Davidson’s ex-girlfriend Cazzie David made a quip on social media about the Saturday Night Lives star new romance with Ariana Grande.

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.

In a photo of the couple shared by comedian Wil Sylvince, who was the show’s first opener, Davidson can be seen holding the sweatshirt, which looks similar to something Grande has shown off on social media before.

When an audience member called out the SNL star for his choice of attire, Davidson — who was also wearing a pair of black and white checkered pajama pants and a trucker hat — remarked, “I smoke a lot of pot — it’s really hard for me to concentrate.”

He also added that while preparing for the evening’s show, “I got very, very high.”

“It wasn’t easy, but I got a great girl, great friends and I consider myself a lucky man. I’ll always be here for you guys, I promise,” he continued, referencing his then-girlfriend David.
