The singer opened up about their friendship, highlighting her honesty and curiosity.“As her friend, I can vouch for her realness, but add that she’s also one of the most empathetic people I’ve ever known,” Swift wrote. “And maybe it’s true that she can’t lie. But I’ll tell you a few more things she can’t do. She can’t stop asking people questions about their lives, endlessly curious about everyone else’s human experience. She can’t stop challenging herself, taking newer and bolder risks like building her production company TeaTime Pictures. She can’t stop exploring the most intricate relationship complexities like in last year’s Splitsville and Materialists. Captivating in front of the screen and inquisitive behind it, her unfailing truthfulness helps to shape her ever evolving storytelling into art that feels as real and timeless as she is. She comes by it honestly.”Over 1,000 guests are expected at Swift’s wedding today. In addition to Johnson, Gigi Hadid, Bradley Cooper, and Benson Boone were just a few of the celeb guests spotted heading to MSG.
