Is there some nasty tension happening with Katy Perry and Robert Pattinson's fiancee?

Did Robert Pattinson & FKA Twigs 'Scream At Each Other' At Recent Event?

On Tuesday, Music News posted details from the GO Campaign Gala when Pattinson showed up with his lover FKA Twigs. The two seemed to have a lovely time together when they caught up with Perry and posed for a photo together. While everything appeared friendly, the pop singer may have been too flirty with the actor, something Twigs would not be happy about.

"Twigs is used to being shoved out of the way by Rob's 'Twilight' fans, but she never expected to get the 'third wheel' feeling with Katy," a source told Britain's Grazia magazine. "Twigs is not the jealous type and Rob has always denied any serious feelings for Katy, but seeing how touchy-feely they were and how Katy was all over Rob would no doubt make Twigs feel uncomfortable."

Meanwhile, Pattinson and Twigs attended a birthday party in London earlier this month where everything seemed to be going just fine. A source told People that the two looked "totally loved-up."

"They are a really cute couple," the source said. "They were cozied up in one of the side booths watching Grace Jones perform, keeping a low profile and chatting away among a group of friends. Then they stood up and danced for a but of the banquette seats. So they were kind of dancing on the tables really."
