Not so fast, everyone!

Rumors have been swirling that Halsey is secretly enjoying a new romance with John Mayer after her split from G-Eazy, but the singer did her best to put the chatter to rest with a Twitter message.

"I just had a ground breaking idea. What if...we let female artists...have friends...without assuming that they are sleeping together? I know I know. It’s like, completely ambitious but like, imagine if we like, tried ?" she tweeted.

The two musicians have been quite flirty on Instagram in recent weeks, though! The "Neon" crooner has been leaving suggestive comments on her sexy posts, and if nothing really is going on, it at least seems that he's doing his best to make something happen!

"It’s saying my billing address doesn’t match with the one on my credit card? I’ve never had this problem before. Can you text me? Thanks," he joked on one of her recent selfies.

The sexy songstress might just be using Mr. Mayer to make her rapper ex jealous!

"Halsey is doing her best to pick up the broken pieces of her heart after her split with G-Eazy, and getting attention from other guys, especially someone as amazing as John Mayer helps. She and John have always had a very flirty friendship so it’s not like she’s flirting with him just to make G-Eazy jealous, but it definitely will," a source dished to Hollywood Life.

"John has always been shameless about hitting on Halsey, even when she wasn’t single he used to openly flirt with her and she used to have to defend their friendship to G-Eazy. So now that all these romance rumors about them have started up it’s bound to bug G-Eazy. But what can he really say, they’re not together and she can flirt with whoever she wants," the source added.

We're not sure we're buying her denial!
