First they were talking about recording a duet together — now Taylor Swift and Lorde are shopping buddies! The two stars were spotted hanging out yesterday afternoon in West Hollywood, California where it looks like they had a blast checking out stores such as Free People and rag & bone. And get this: They spent the day before together too, hitting the beach to go for a barefoot walk in the sand! That's a lot of bonding time!

While we're glad to see Taylor and Lorde having so much fun, we can't help but wonder how Selena Gomez — who has a troubled history with the New Zealand-born pop star — feels about their fast friendship. Sel's been going through such a difficult time lately; we hope that seeing one of her besties hanging out with someone who publicly dissed her in the past isn't too hurtful.

Are you surprised Taylor and Lorde are becoming so close? Do you think Selena has a right to be jealous? Sound off in the comments!
