Are Robert Pattinson And Katy Perry Getting Flirty?

Rob and Katy spotted at karaoke bar...oh yeah, together...

Oh Robert Pattinson, how we've missed reporting on you every day. Since just after New Moon's in-theater release, Pattinson has kept a pretty low profile between New York and L.A. Wednesday night, however, he was spotted out in Burbank with none other than Katy Perry, and it's said she was giving Rob an "eyeful." What's the story?!

Apparently the pair are regular karaoke buddies at Dimples Supper Club in Burbank, a spot that's known for its bad karaoke and celeb sightings. A source says, "She brought [Pattinson] here before. Every time she comes he seems to follow."

What's the attraction? Well, they have a lot in common. Both are high-energy, rebellious performers with large British and American followings, plus each loves objects of affection from the other's culture. American Katy is with British comedian Russell Brand and British Robert P is with all-American girl, Kristen Stewart.

Rob and Katy showed up late Wednesday night with friends, and Katy took to the stage to sing a Christmas song that apparently didn't go very well due to trouble with the bar's speakers. But Radar Online has a witness saying, "She had on black skin tight pants with the sides cut out, Rob was getting an eyeful and he loved it!"

Sounds like one man's chemistry is another girl's friendship. It's said they were talking with their foreheads touching and Katy Perry was giggling and "positively giddy" around Rob...the footage that Radar has sort of shows her bitching him around the backseat of her Audi, but that could be because when he left the bar, it's reported he was "feeling no pain."

So, wait...Kristen Stewart doesn't do karaoke? And if Katy Perry's hanging out with Robert Pattinson, then why was Russell Brand shopping for Cartier diamonds in London before flying to L.A. this week?

We love Brit-American romances!
