Hailey Baldwin is making her marriage to Justin Bieber Instagram official! On Friday, the 21-year-old model changed her username to @haileybieber [1], with her full name reading Hailey Rhode Bieber. At the moment, her Twitter [2] and Facebook accounts [3] still read Hailey Baldwin. The Instagram name change comes just a day after Hailey was spotted sporting a custom "Bieber" jean jacket [4] at Levi's Time Square opening party in New York City.

Hailey and Justin first rekindled their romance in June [5] before tying the knot in September [6] at a courthouse in NYC. Though they were initially mum about their wedding ceremony, they eventually confirmed their marriage [7] to a fan in October. See some of Mr. and Mrs. Bieber's cutest moments together ahead.
