What's going on here?!

Halsey left a cryptic comment on ex-boyfriend G-Eazy's Snap the other day and people are freaking the F out ... and so are we, kinda. After G wrote "Big D Energy," Hals posted a series of emojis -- a cloud, a tornado and then a raindrop. Fans called out Halsey for throwing shade even though no one can figure out exactly what her emoji message meant!

The 23-year-old singer responded to a fan who thought she was dissing G, "No petty here. Caption dumb funny and stage looks dope. Jealous of everyone who gets to see the show!"

Halsey announced her breakup with the 29-year-old rapper on July 3 and even cried during a performance of "Sorry" when the lyrics "Someone will love you / But someone isn’t me" kicked in.

Last week, Demi Lovato was seen with Eazy and the rumor mill kicked in but G denied the two were anything but friends and told Entertainment Tonight at the ESPY Awards that the false reports are to be expected: "It’s just one of those things that comes with the territory. You trade in your anonymity in exchange for some of your success in the public eye. You have to remember the blessings and remember how grateful you are to be here in the first place and understand that some of that is just what comes with the territory."
