Hailey Baldwin has changed her name to Hailey Bieber on Instagram. The model's verified social-media account now says, "Hailey Bieber." The move came after singer Justin Bieber shared a photo of him with Baldwin on his own page captioned, "My wife is awesome." E! News said the couple got engaged in July and were spotted at a New York courthouse in September. Baldwin denied two months ago on Twitter that she and Bieber had gotten married, then deleted the message. Their recent posts suggest they may have since tied the knot.
