Hailey Baldwin has changed her surname to Bieber on social media.
The 21-year-old model seemingly confirmed she was married to Justin Bieber by changing her Instagram handle to Hailey Rhode Bieber on Friday.
Her new name comes after she filed to trademark her married name last month.
For the purposes of a clothing line, Hailey registered her maiden name, the moniker Hailey Bieber, as well as HRB3 - a combination of her middle name, Rhode, and her mother's maiden name, Deodato - under her company, Rhodedeodato Corp.
Hailey and popstar Justin are yet to confirm reports suggesting they tied the knot in September, but they have been referring to each other as "husband" and "wife."
Rumours that the couple, who became engaged in July, had married were sparked after they were spotted visiting a courthouse in Manhattan.
Hailey hit back at the speculation at the time, insisting she was still not married, but a source told reporters at Entertainment Tonight that they will hold a more formal wedding for family and friends later this year.
"Justin and Hailey wanted to be married, and didn't want to wait. They still plan to have a more formal wedding, but for them, this intimate ceremony was exactly what they wanted," the insider explained.
Hailey recently stepped out wearing a jacket with "Bieber" adorned on the back in New York City, and she couldn't help but gush about her beau in an interview with Harper's Bazaar.
"He is incredible," the blonde star smiled. "He crushes everything. Every song, every feature. It's crazy to see what he does... I'm always blown away."
