Who knew she was so popular?!

Selena Gomez arrived back in LA from London on Friday afternoon, and she was greeted by complete fan chaos! There was a huge crowd waiting to meet her and score autographs, and while we think the "Come & Get It" songstress is great and all, she's not someone legendary like Britney Spears!

The brunette beauty was across the pond for Paris fashion week, but she squeezed in some work as well! Justin Bieber's ex took care of some promotional appearances in England for her new movie Neighbors 2: Sorority Rising, and she also spent some time plugging her upcoming Revival tour, which kicks off May 6 in Las Vegas.

We wonder if The Biebs ever misses her?
