Ariana Grande chatted with Ryan Seacrest on his radio show on Thursday, but rather than a nice gabfest, the interview turned ugly when he asked about her relationship with Mac Miller! (Actually, she was acting a bit testy before that, but apparently that's just how she is, right?)

Seacrest implied that the pop star made her romance with Miller public with an Instagram photo last week, and it REALLY rubbed her the wrong way. "Oh, is that what I did? Is that what Instagram means to you now?" she said. "All right world, let’s go." Seacrest replied that he didn't know, which is why he was asking. "What are you asking? You said a sentence, there was no question," she sniped.

"It's like, 'Good morning, On Air With Ryan Seacrest,'" she continued. "It’s too early for this kind of tea. It’s too early, man." Seacrest wouldn't let up -- and we love him for that! "That's what we do," he said. "If you post something — even in my life — if I post something, it becomes something."

Grande replied, "If I post something, then that’s what I’m willing to share at the moment. That doesn’t mean that you, Ryan Seacrest, with millions of listeners, are entitled to more information." Haha! Clearly she doesn't understand how it works...

Grande and Miller attended the MTV Video Music Awards together, and last month they were spotted kissing during a dinner date in Encino. And yeah, there's the whole Instagram photo Seacrest is referencing, where she calls him her "baby."
