She's not wasting any time!

Halsey was spotted getting cozy with British rocker Yungblud on Tuesday, and it seems that she's already putting ex G-Eazy on the back burner in the wake of their recent split.

The 24-year-old songstress and the 20-year-old bad boy were spotted arm-in-arm after a recording studio session, and Yungblud even bought his new lady some flowers. Now that's how a boyfriend should treat their girlfriend!

Apparently G-Eazy isn't having an easy time letting go of their relationship, though!

“G-Eazy is still missing Halsey like crazy, but he’s doing his best to move on since their painful breakup. It’s difficult for him seeing how incredible she’s doing, and how amazing she looks. But G-Eazy still cares about Halsey and a piece of him will always love her, so he just wants her to be happy," a source dished to Hollywood Life.

"G-Eazy knows Halsey can get any guy she wants, which makes moving on that much harder. He is casually dating around and he’s certainly not ready to jump into a new relationship anytime soon. Right now, G-Eazy is just looking for a distraction to help heal his heart and adjust to life without Halsey," the source added.

We guess she was telling the truth about just being friends with John Mayer!
