Halsey and John Mayer?!

Is Halsey cozying up to John Mayer following her split from G-Eazy? The longtime friends have been spending a significant amount of time together virtually and in real life.

Halsey, 24, recently Instagrammed a video of herself FaceTiming Mayer while out for a drive, captioning the clip, “7am carpool karaoke with John Mayer.” Fans have spotted Mayer, 41, in Halsey’s Instagram comments on several occasions.

He recently popped up among her fans to ask for a little IT support from Halsey on Monday after she posted an ad for a YSL Beauty Lipstick.

“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,” he wrote. Halsey was quick to quip back, “@JohnMayer wrote u a song with the help hotline # in the chorus. Sending mp3 now.”

Even when he wasn’t commenting on Halsey’s photos, Mayer has hit the “like” button on several of her photos, including one of her sporting her Poison Ivy costume for Halloween and others.

Fans got especially curious about the flirtation between Mayer and Halsey on October 16th, when she shared a screenshot of the text she drunkenly sent him on what she thought was his birthday. In it, she gushed about how being “lucky to have dipped the smallest toe into your waters. Blessed to even watch your current from afar.”

The pair have long been rumored to be an item and have been quick to shut down speculation – and this time is no different. On Wednesday, Halsey tweeted: “I just had a ground breaking idea. What if…we let female artists…have friends…without assuming that they are sleeping together?” She added “I know I know. It’s like, completely ambitious but like, imagine if we like, tried?”
