Halsey and John Mayer have been pretty flirtatious with each other on Instagram recently.
This week, Halsey posted a Facetime with Mayer in her Instagram Stories calling it "7 am carpool karaoke with John Mayer."
Mayer was all in Halsey's comments section for a post about YSL Beauty lipstick.
Mayer said, "It's saying that my billing address doesn't match with the one of my credit card? I've never had this problem before. Can you text me? Thanks."
Halsey responded, "wrote u a song with the help hotline # in the chorus. Sending mp3 now."
Obviously they're not officially dating but you already know everyone has already assumed that they have something going on.
