When it comes to Taylor Swift, we know three things to be true. One, she has a seriously covetable girl squad. Two, she has a Tribeca penthouse most of us will only ever dream of living in. And three, she LOVES to throw a party. What do you get when you combine these things together? A killer house party, obviously. The pop star threw herself an epic birthday bash back in 2014 at her place in NYC and the most A-list Fourth of July celebration we’ve ever seen last summer at her mansion in Rhode Island. With her tour finally wrapped and a rumored break on the horizon, we’re thinking a massive slumber party is in order. What makes us think this is on Tay’s weekend calendar? Let us take you through our very detailed investigation process.

Yesterday Taylor was spotted in Beverly Hills buying more pillows than we’ve ever seen someone buy in one go. In fact, she bought so many she had to recruit a “pillow handler” (see a pic of said handler here). What could Taylor Swift possibly need this many pillow for besides the most epic sleepover that ever was?

While her ultimate celeb bestie Selena Gomez won’t be celebrating her bday until July, Taylor gave a birthday shout out to her childhood BFF Abigail Anderson just three days ago. Last year Taylor threw Abigail a party complete with a personal performance by Dashboard Confessional’s Chris Carrabba. Could she be working on yet another epic way to celebrate her BFF? We’re saying yes.
