Talk about awkward. According to Just Jared, Kristen Stewart recently attended Katy Perry’s birthday party … without Robert Pattinson by her side.

Let us refresh your memory on this one: After Kristen cheated on Rob, Katy was rumored to be his rebound girl. And now that Kristen and Rob are back together again, Kristen is attending Katy’s party on her own?

Something seems off here. We half expect to hear about some huge throwdown. Although, that doesn’t seem to be Kristen’s style.

Regardless, on Oct. 19, Kristen headed over to The Magic Castle with Rob’s friend Marcus Foster. Although it was a costume party — Katy was a vampire (like we said … awkward) and John Mayer was a zombie hunter — Kristen didn’t dress up.

“She looked happy and was surrounded by her friends the whole time,” a source told Just Jared about Kristen.

Maybe Kristen was more focused on reconnecting with Rob’s other friends than dealing with Katy? Do you guys think it’s odd that Kristen went?
