Nov. 18 (UPI) -- Model Hailey Baldwin has changed her last name to Bieber on Instagram.
Her verified social-media account now says, "Hailey Bieber."
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.
