Katy Perry feels that she has been bumping into One Direction singer Niall Horan quite a lot, so she jokingly called out the young crooner for being her stalker.

The two came face-to-face backstage at “The Voice Australia” on Sunday, where they were both making guest appearances, according to Entertainment Tonight.

“You're following me!” Perry teased Horan while she was making an Instagram story that included the label, “stage 5 clinger.”

“I am - everywhere,” Horan teased in return.

Perry earlier said on the Australian morning radio show Fitzy & Wippa on Nova 96.9 FM that Noran has a crush on 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 said.

Even though things will never work out romantically between the two, Perry said she has a special bond with Horan. “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 explained.

As far as Perry’s romances are concerned, she was previously linked to musicians like John Mayer and Diplo and actors such as Orlando Bloom. During a talk with James Corden during her 72-hour YouTube livestream, the singer got candid about her love life and even ranked her ex-boyfriends from best to worst in terms of their abilities in the bedroom.

Perry and Corden played a question and answer game in the livestream, and the rule was for Perry to answer a question from Corden or eat a questionable snack. When asked about her ex-boyfriends’ prowess in the bedroom, the 32-year-old pop star decided to weigh in. “They’re all amazing lovers and I would have sex with all of them after I get out of this place!” she said.

“Working on the notion that they’re all good,” Perry ranked Mayer as her No. 1, followed by Bloom. Diplo ranked last.
