Halsey is flirting up a storm with Taylor Swift's ex-boyfriend

So much tension.

By Bianca Mastroianni

The great thing about being a celeb is that you can slide into other A lister's DM's very damn easily. So when celebs publicly ~flirt~ online, we can't help but wonder if they want us to see it and come up with these stories.

Over the weekend, Halsey made a tweet about Calvin Harris and his gorj voice.

"Honestly @CalvinHarris singing voice makes me feel warm inside," she said. Same, really.

Calvin didn't miss a beat, replying to her in the cutest way possible.

"@halsey ur a sweetheart 🙏". Obvs everyone started to ship the pair straight away. That, or begging them for a collaboration.

We're all about that.
