Katy Perry, who reportedly split from John Mayer, allegedly posed a threat to Robert Pattinson and FKA Twigs.

"Rob and Katy were spotted out and about together numerous times, and he never seemed happier than he was when they were hanging out," said Celebrity Dirty Laundry.

"Whispers among Robert's inner circle tease that he and Katy Perry are growing close again, and they still have an amazing chemistry between them," it added.

But Gossip Cop claimed that there's no such thing.

"There's nothing accurate in the entire CDL story," it said. "Pattinson does not 'regret' proposing to FKA Twigs, and he was never 'hooking up' with Perry. Knowing full well how certain untrustworthy sites operate, Gossip Cop even wrote on Friday, when reporting on the Go Campaign event that we 'would not be surprised if some particularly bad webloids try to heat up fake romance rumors between Pattinson and Perry.'

There's no apparent tension between FKA Twigs and Katy Perry either, as they even posed with Robert Pattinson during the 8th Annual GO Campaign Gala in Los Angeles on Thursday night.

"All three stars are dressed to the nines with Perry, 31, wearing all black with a dark lip and jet black hair," People said. "The couple complemented each other with Pattinson in a simple black tux and white button down and a black tie, while his lady wore a textured white number with her hair in an updo and sported a peachy-pink pout."

The rumors linking Robert Pattinson to Katy Perry are not new, even before the "Twilight" star met FKA Twigs. In last year's Coachella, for example, the two allegedly hooked up.

"Katy and Rob are the best of friends with a very strong sexual chemistry," said Glamour. "Friends genuinely want to see them get it together properly. They think they bring out the best in each other."

But FKA Twigs has nothing to worry about as Katy Perry insisted that she's just friends with Robert Pattinson, whom she calls her "bud."
