Taylor Swift clapped back at critics who think she should "go away" while stopping by The Late Show With Stephen Colbert to promote her upcoming Eras Tour docuseries, The End of an Era. The pop superstar, 35, appeared on the Wednesday, December 10, episode of Stephen Colbert's CBS late night show, stepping onstage in a burgundy velvet mini dress by David Koma. She paired the festive look with pointy heels (also in burgundy velvet) and a sparkly necklace. Swift's hair was pulled into a sleek chignon and, naturally, she sported her signature red lip to match the outfit.
