Cazzie David, Pete's ex -- whom he dated for years -- knows it, too.
And she's sending a message loud and clear by flaunting her mind-blowing revenge body in a bikini.
Sporting a red-hot bikini and a hotter body, Cazzie David is flaunting her epic bikini body to full effect.
Cazzie captioned her epic thirst trap: "Idk. Beach?? Summer? ? [red heart emoji]?? W/e"
By the red heart emoji, we assume that she is teasing the possibility of romance or love.
(And "W/e," by the way, just means whatever)
Once they lifted their jaws off of the ground and were capable of processing complex thoughts again after looking at this gorgeous pic, many people arrived at the same conclusion.
Cazzie David is reminding Pete Davidson of what he's missing.
See, Cazzie David is the daughter of comedian and Seinfeld creator Larry David.
Cazzie is also a comedian in her own right.
But, though she is perhaps best known for her career and for her father, she is also Pete Davidson's ex-girlfriend.
In fact, the two of them dated for nearly three years.
And it was a very short time -- like, about a month -- between Pete and Cazzie's breakup and Pete and Ariana's engagement.
Cazzie made a subtle reference to Pete's relationship with Ariana on instagram, posting a caption that was a clear nod to the news.
In the post in early June, Cazzie wrote: "Been in Africa, what’d I miss ??"
That's a cute way of acknowledging that you know about something without stirring up any additional drama.
But that, of course, was before the news came out that Pete had proposed to Ariana and Ariana had said yes.
Even if you love Pete and want what's best for him and admire Ariana and want her to get the happiness that she deserves, you have to admit:
This whole thing is probably a little weird for Cazzie.
Some people have gone on vacations that last longer than the space between Cazzie's breakup with Pete and Pete's engagement to Ariana.
That said, we don't know that her flaunting her body on Instagram is necessarily a ploy to give Pete a walk down memory lane.
Sometimes you're hot, and you just want to show it.
If anything, Cazzie might be reminding the world that she's young, hot, and will have no problem finding new love, new experiences, and a new man -- if and when she chooses to.
Good for her.
Some are still weighing in on how long Ariana and Pete will actually last.
It's possible that they could break off their engagement as soon as the honeymoon phase of their relationship is over.
You come down from that hormonal high and you discover that things aren't working out. That can happen in months or in years. Or in decades.
But we don't expect to see Cazzie David waiting around, pining after Pete to take her back.
She has her own career and her own life, folks.
