Their long-running feud all stemmed when Kim K shared a naked selfie and Chloe called her out for showing off her body.
“I truly hope you realise how important setting goals are for young women, teaching them we have so much more to offer than just our bodies,” she tweeted.
This didn't go down so well with Kim, who clapped back: “Let’s all welcome @ChloeGMoretz to twitter, since no one knows who she is. your nylon cover is cute boo.”
So when Kim released her new perfume on Valentine's Day, naturally she sent a gift to her "lovers and haters" - including Chloe.
And if you've ever wondered what Chloe did with the gift (and if you're like us, you definitely would have) you'll be glad to know Chloe has finally spilled the beans on where it ended up.
"No, I never saw it," she told host Andy Cohen on Watch What Happens Live.
"I literally got a video of it from my publicist. They’re like, ‘They sent this so we just kept this.’ I was like, ‘Okay. Cool.’ But, thanks?"
Hmmph. Guess the end of that then.
