Shortly after the break-up, Ariana debuted her chart-topping single "Thank U, Next" in which she name-checks Pete as well as a number of her other ex-boyfriends, expressing her gratitude for what each of the relationships taught her.
"I'm writing to you this February 22, 2018".
In a previously shared teaser for the "Thank U, Next" music video, Grande made a joke about her split. You now know our schedule for each of those dates: watching the episodes on repeat. Kris Jenner is, of course, pop culture's ultimate overprotective momager - and we love her for it. Grande's former Victorious co-star Matt Bennett also appears as Cliff Pantone from Bring It On.
Then comes that cheerleading classic Bring It On and its cheer-off between the Toros and Clovers.
In her Legally Blonde entrance, Grande drives a Porsche with a licence plate that says "7 Rings" - the internet thinks this is a reference to friendship rings she and her six best friends have.
The Telegraph Ariana Grande performs during her One Love Manchester benefit for victims of the bombing at her concert in 2017. And, yes, there's Elle Woods' BFF Paulette. One important note for serious Ariana fans: the vehicle has a vanity plate reading "7 RINGS", which is allegedly another track from a forthcoming album. It's really great to see Ariana Grande stand up for this in a music video that will be seen by, well, probably billions. Just like in the film, the two chat about their exes, with Grande once again making a "Pete has an above-average penis" joke.
What he'll always remember, however, was seeing Ariana step into one of her favorite films.
