These two seem quite taken with each other!

Katy Perry and Niall Horan bumped into each other while both appearing as guest judges on The Voice Australia on Sunday, and the pop star accused the former boybander of being a "stage 5 clinger" and stalking her! Of course, it was all in good fun, but we're starting to wonder if those romance rumors might be true.

KP even recently implied that the British hunk has the hots for her!

"I see [Niall] around all the time. He's always trying to like, get my number, to like, maybe flirt with me but I'm like, 'I could babysit you. I'm like your mom!'" she told the Australian morning radio show Fitzy & Wippa.

"Niall's amazing, I love him, and I think we feel very connected in a way because I, like, helped him get through The X Factor to join his group. He's become a big star and I'm like, 'Cool, I guess that means I have taste?' I don't know what that means," she clarified.

The "Smooth Hands" crooner was more than happy to play along.

"Katy, please stop being mean to me. She's just finding any excuse now to just patronize me and go around spreading rumors about me. I just want to be your friend! I mean, she is talking like she is about 55 years older than me. She is not that much older than me," he joked on The Project.

This kind of witty banter could easily turn into a real relationship!
