Taylor Swift is the queen of dropping Easter eggs in her work, so it’s no wonder her new “The Life of a Showgirl” album — which debuted Friday — is riddled with hidden surprises. “I can’t tell you how proud I am to share this with you, an album that just feels so right,” the singer wrote on Instagram after her latest project was released. “A forever thank you goes out to my mentors and friends Max and Shellback for helping me paint this self-portrait.”
