Kristen Stewart and Alicia Cargile landed at Los Angeles International Airport on Thursday evening, and rather than taking yet another romantic vacay, the ladies were attending the wedding of K. Stew's bestie, Riley Keough. If the Twilight starlet is bringing Alicia as her date, things MUST be serious!

Riley got married in Napa, California on Wednesday, and rumor has it she's the main pal who's encouraging K. Stew to come out with her relationship! "Riley knows Kristen would be happier if she stopped hiding her feelings," a source tells In Touch. "She told Kristen she shouldn’t hide who she is and who she loves."

K. Stew was notoriously private when she was with former flame Rob Pattinson, but it looks like we'll be seeing even more of the actress and her girlfriend because the mag also reports that they're moving in together! "Kristen recently bought a huge loft in downtown LA and she asked Alicia to move in," an insider tells the publication. "It seemed pointless to live apart, since they were with each other every day."

Aww, it seems like K. Stew really has moved on from R. Pattz!
