Model Hailey Baldwin appears to have confirmed her marriage to Justin Bieber by changing her Instagram name to Hailey Bieber.

Justin has also shared a picture of the couple together with the caption: "My wife is awesome."

Baldwin and the singer are believed to have gotten married in secret in September, according to the BBC.

She has adjusted both her online handle and her bio. Rumours abounded that the couple had married in New York two months ago but she has denied any such ceremony at the time.

24-year-old Bieber and 21-year-old Baldwin announced their engagement in July. Bieber wrote on Instagram: "Hailey I am soooo in love with everything about you!

"So committed to spending my life getting to know every single part of you loving you patiently and kindly.

"My heart is COMPLETELY and FULLY YOURS and I will ALWAYS put you first!

"You are the love of my life Hailey Baldwin and I wouldn't want to spend it with anybody else."
