As part of Vanity Fair's lie detector test, Wicked costars Ariana Grande and Cynthia Erivo grilled each other. At one point, Grande was asked whether she had plastic surgery -- including a nose job, chin implant, eye lift, boob job or BBL -- and revealed all she's done was Botox or fillers, but stopped 4 years ago. During the test, the pair also spoke about fans, whether the moon landing was fake, what they binge-watch, astrology, which celebrities left them starstruck and more.
