Kristen Stewart seems like she's having a pleasant time hanging out with her perhaps more-than-friend Alicia Cargile, which is nice for her.

For weeks, blogs have been passing around sexy rumors about Stewart's relationship with her live-in buddy Alicia. They went to Hawaii together, for instance, and what does that mean? Kristen had her arm on Alicia at one point, etc., etc. Now a source tells Radar that the pair got matching arrow tattoos! They sound fun. From Radar:

"They are inseparable and mimic each other's everything," a friend of the Twilight actress tells RadarOnline.com exclusively regarding their matching right-arm tattoos of arrows pointing in the same direction.

"Helloo...my naaame...is...Kristen...Stewart!" —Kristen Stewart and Alicia Cargile simultaneously, one can bet. The source went on to Radar about the girls' trip to Hawaii:

"When Kristen and Alicia were in Hawaii for New Years, I am sure that they thought no one was going to see them," the insider says. "But they are not exactly nonchalant about their relationship anymore."

Of course, why be nonchalant (?) about something that seems so chill and fun? And finally, the source spoke about Kristen Stewart's self-assuredness:

"Kristen is happy and she is just being herself. She doesn't need to worry about where her next role is going to come from nowadays because she has proven herself as an actress," the source adds.

That sounds nice. Kristen and Alicia seem like they have a nice thing going.
