WENN 1 / 15

Over the years, longtime pals Robert Pattinson and Katy Perry have repeatedly brushed off attempts to link them romantically. But they sure seem to enjoy each other's company. Page Six says Rob, 28, and Katy, 29, were "looking cozy" last Friday during a post-premiere party in Los Angeles for his well-received movie "The Rover."

The doll-faced popster reportedly snuck into the shindig at hotspot Whiskey Blue through the kitchen and made a beeline for the patio.

"Later on, Robert joined her," says a spy, with another observing, "They were heavily flirting. At one point, Robert sauntered to the bar with a pal and was heard saying, 'She's so [bleeping] hot,' nodding in Katy's direction."

While insiders assure Gossip Cop that the pair's relationship remains platonic, perhaps the British actor has a weakness for women who are in touch with their bodily functions.

"Okay, so here's the proof there was never anything going on with me and Robert Pattinson," Katy explained to the September 2013 issue of Elle UK, when asked about the romance rumors. "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."

What's more, "He's my bud, I'm like his big sister," she insisted. "We just hang out. The other day, I said, 'One of the things I'm most proud of is not sleeping with you, Robert.' And that's true."

Perry, who since her February split from John Mayer has been linked to DJ Diplo, rapper Riff-Raff and rocker ex-boyfriend Robert Ackroyd, has said she even contacted Pattinson's repeat ex-girlfriend Kristen Stewart to tell her the hookup talk wasn't true: "I sent her a text message saying, 'I know you've seen all this stuff, but you know I would never disrespect you. I'm not that person.'"
