Davidson told Howard Stern that he started dating Ariana Grande on the night of the Met Gala on May 7, 2018, when the pair hung out with friends at Grande's NYC apartment.
The "7 rings" songstress had met the "SNL" star when she first appeared on the show to perform back in 2014 but did not become close until she appeared on the show again in 2016. Grande had been dating the late rapper Mac Miller at the time.
Grande confirmed she'd split from Miller in a post on her Instagram Story on May 9, 2018, and in the coming weeks, Grande and Davidson were spotted together on various occasions, even sporting new matching tattoos. They also commented frequently on each other's Instagram accounts.
They didn't become Instagram official until later that month when they dressed up in "Harry Potter" outfits in a since-deleted post on Davidson's account.
Days later, on June 3, Grande was spotted wearing what Us Weekly and TMZ reported to be an engagement ring, but the couple didn't confirm they were engaged until June 20, when Davidson appeared on "The Tonight Show Starring Jimmy Fallon" and announced their engagement.
A summer romance ensued, with the couple moving into Grande's New York City apartment together and adopting a pet pig that they named Piggy Smallz. Grande even dedicated an interlude on her album "Sweetener" after her new fiancé, naming it "Pete Davidson."
They made their red-carpet debut at the 2018 MTV Video Music Awards on August 20, exactly two months after confirming their engagement.
Then, in September, they announced plans to take a break from social media.
At the end of that month, Davidson joked about the couple breaking up on "Saturday Night Live." A few weeks later, in October, reports confirmed the couple had split, with Davidson discussing the split in the following weeks during his stand-up shows and on "SNL."
Then, on November 3, Grande released her breakup anthem "thank u, next," mentioning all of her famous exes by name, hours before Davidson addressed his split on TV.
