There’s no night like a girls night, especially when it involves Selena Gomez and Taylor Swift! That’s how the very lucky Fifth Harmony singer, Camila Cabello, celebrated her big 1-8. Camila Cabello celebrated her 18th birthday on Tuesday night, March 3, with a gorgeous group of gal pals including Selena Gomez, 22, Taylor Swift, 25, a pregnant Jamie King, 35, and Hailee Steinfeld, 18. The Fifth Harmony songstress rocked a princess crown while posing with her girlfriends, and everyone looks like they had an amazing time. Plus, we just love seeing Selena and Taylor back together!
