Reports are surfacing that a Bjork concert over the weekend in LA had a couple of extremely famous faces in attendance, namely, the probably-more-than-friends duo of Katy Perry and Robert Pattinson. Though they were both there, the two also made sure not to make a public appearance together.

"Apparently a lot of people love Rob Pattinson! He was with friends, just enjoying the show," fan Poppy Livingston tweeted. "Saw Rob Pattinson at Bjork tonight! Nice guy!."

Though the two did not party together for most of the night, it was clear that they both knew the other would be going and even coordinated efforts to sneak in a little one-on-one time with each other.

"They had planned to meet up before going inside to the concert. They must have been coordination on their cellphones because they pulled up next to each other in the parking lot, rolled down the windows and were talking. They parked and then met at the door and went inside together," said one eyewitness.

Such actions only add fuel to the fire over rumors that Pattinson and Perry will soon be an established couple. Though they have kept quiet on the subject so far, their avoidance of the issue and careful control over the image of the relationship is a bit suspicious.

"Katy came out the back door by herself, trying not to be noticed. She was looking around to see if there were any photographers. She definitely didn't want to be shot with Rob," the eyewitness continued.

Pattinson and Perry have been friends for quite some time now, and it was Perry that Pattinson went to after being publicly embarrassed over his then-girlfriend Kristen Stewart's affair last year with director Rupert Sanders.

Perry has suffered through some serious heartbreak of her own, coming off a disappointing divorce from comedian and actor Russell Brand. Both Perry and Pattinson have been described as "hopeless romantics" and it appears inevitable that they will start up a relationship, despite their hesitancy to publicly do so.
