Taylor Swift's now as recognizable for her fabulous feminist friends as she is for her monster 1984 singles like "Shake it Off" and "Blank Space." And the princess of pop has a new inductee into her pal circle—Fifth Harmony's Camila Cabello.

Cabello turned 18 yesterday and celebrated with the likes of T-Swift, Paramore powerhouse Hayley WilliamsSelena GomezHAIM and even some actresses, among them Hailee Steinfeld, Jamie King and Sarah Hyland.

Tay and Selena both posted pictures from the gathering (peep 'em up top). While it looks like the rest of 5H weren't at the get-together, each member posted an adorable Camila pic on their personal Instagrams.
