Imagine if your idol threw you a birthday party — scratch that — imagine if Taylor Swift threw you a birthday party. It'd probably be the best birthday of your life. On March 3, Fifth Harmony singer Camila Cabello was lucky enough to live that dream!

Now we know how the whole magical bash came to be: In a new interview with MTV, Camila dished that when she told T. Swift that she hadn't planned anything special for her 18th birthday, the "Blank Space" singer instantly flipped into fairy godmother mode. Taylor then invited Camila over for what resulted in the coolest impromptu birthday bash we've ever seen.

The party was chock full of party hats, and the guest list hosted some of our favorite leading ladies including Jamie King, Hayley Williams, Selena Gomez, the Haim sisters and Sarah Hyland. Cabello mentioned to MTV that she'd recently texted Tay about Rosco's Chicken and Waffles and, lo and behold, Taylor had some ready when she arrived!

The rest of the Fifth Harmony girls were just as excited as Camila. Dinah Jane even exclaimed, "Your friggin' idol celebrated your birthday with you!"

You can see some of the adorable birthday snaps on Taylor's Instagram. If only she could be everyone's fairy godmother.
