She also admitted that she recently slept with an ex and deeply regretted it, dishing to fans before performing Sorry:

“I learned recently it’s okay to be alone! Being alone is enough. The second lesson I learned is don’t sleep with your ex.”

Wait a minute. Could she be talking about those rumors that she recently rebounded with alleged former fling Machine Gun Kelly!?
Or maybe it was a different ex…
Either way, sounds like she’s learned a lot recently.
Halsey performed inside Premier Nightclub at Borgata following her show, during which she told all the singles in the crowd that everyone has to go home with someone — but she’s not. Message received!
Do U think Halsey was admitting to rebounding with MGK?
