Hello, Mrs. Bieber! Hailey Baldwin Officially Changes Her Name on Instagram

Hailey Baldwin is making her marriage to Justin Bieber Instagram official! On Friday, the 21-year-old model changed her username to @haileybieber, with her full name reading Hailey Rhode Bieber. At the moment, her Twitter and Facebook accounts still read Hailey Baldwin.

Hailey and Justin first rekindled their romance in June before tying the knot in September at a courthouse in NYC. Though they were initially mum about their wedding ceremony, they eventually confirmed their marriage to a fan in October. See some of Mr. and Mrs. Bieber's cutest moments together ahead.
