Taylor Swift let 500 of her fans in on a secret.
On Nov. 10, the 27-year-old singer will release her sixth studio album, Reputation, but about a month ago, she surprised a bunch of Swifties by hosting listening parties at her homes in London, Los Angeles, Nashville and Rhode Island.
An attendee at the L.A. secret session told ET that some of Swift's famous friends were at the soiree, including Ruby Rose and music producer Jack Antonoff. As for her house, the partygoer called it "gorgeous."
"She's in the middle of renovating," the attendee noted. "It's just got deemed as a historical landmark because it's the old MGM house."

Swift also greeted and posed with her fans, which left many of those interviewed breathless and nearly in tears.
"I mean, she just felt like she was my friend," another Swiftie said, holding their heart. "There's no way to describe it. It was just like everything I could have asked for and more."
