It looks like Kristen Stewart and Robert Pattinson may have gone their separate ways- at least for the weekend.

Robert Pattinson Wears Cologone To Feel Like An Adult?

On Sunday, Celebuzz took a picture of Pattinson at Cochella's H&M Loves Music Party in Indio, Calif. where he supposedly made an appearance with none other than pop star Katy Perry.

In a photo with some bright lighting and a bit of blur, the two can be seen as they stand near each other. According to an eyewitness, they arrived separately about 10 minutes apart at about 1:30 a.m. Apparently, the two met up during Major Lazer's set in the VIP section where they reportedly shared a hug.

Kristen Stewart Trying To Win Ex Back?

While this creates speculation if there's something romantic going on between the two, a source recently told Hollywood Life that the Twilight star and Unconditionally singer are just friends.

"They are two beautiful, flirty and charismatic people and when outsiders look at it, that makes it look like they must hook up," the source said. "But the truth is they have always been with someone so they have become great friends instead. Anytime that it had the chance to become more has passed."

According to another source, it seems that one of the reasons for the stars' close friendship is due to difficult breakups they each had to face.

"Rob has absolutely no interest in hooking up with Katy," the source revealed. "They are close friends, but that's it. she was there for Rob when he split with Kristen and he's been helping her deal with getting over John, like offering advice, but that's it."
