"Twilight" star Robert Pattinson seems to be interested in "roar" singer Katy Perry, after rumors claimed that the two were spotted canoodling with each other at an LA-after party for his upcoming movie "The Rover."

The insider told New York Post's Page Six, "Later on, Robert joined her on the patio. They were heavily flirting. At one point, Robert sauntered to the bar with a pal and was heard saying, 'She's so f****ng hot, nodding at Katy's direction."

However, just last month, Pattinson was romantically involved with 220-year-old model Imogen Ker, while Perry was linked to DJ and music producer Diplo, according to the Daily Mail.

Although the couple has not yet confirmed the actual status of their relationship, Perry previously dished that she only sees Pattinson as her little brother.

"He is my bud, I'm like his big sister. We just hang out." In a previous interview, Perry explained directly to Pattinson, "One of the things I'm most proud of is not sleeping with you, Robert. And that's true."

In a separate interview with Elle magazine, Perry shared, "OK, so here's the proof there was never anything going on with me and Robert Pattinson. I fart in front of him. Properly fart. And I never, ever fart in front of a man I am dating. That's a rule."

Meanwhile, Pattinson, who was previously in a relationship with his "Twilight" co-star Kristen Stewart ended their relationship some time in 2012.

Multiple sources confirmed that one of the reasons why Pattinson and Stewart ended their relationship was because of Perry, the Hollywood Gossip noted.

At that time, Perry contacted Stewart and said, "I sent her a text message saying, 'I know you've seen all this stuff, but you know I would never disrespect you. I am not that person. I'm just trying to be a friend to him, but it is unfortunate that I do have a set of t*ts.'"
