Hailey Baldwin is Mrs Justin Bieber now

There had been rumours that the couple had got married in a NY two months ago but Hailey denied it at the time.

Bieber posted a picture of him and Baldwin on his Instagram and captioned it, "My wife is awesome".

As if that wasn't enough, Hailey has now officially changed her last name to Bieber on Instagram.

"He is incredible", Baldwin said of the pop star.

Still, we hope that Hailey never has to change her name back.

The couple, who rekindled their relationship in May after Justin split from Selena Gomez, got engaged in July after the Biebs got down on one knee in the Bahamas. Justin and Hailey wanted to be married, and didn't want to wait.

It seems like Hailey is really embracing her married life with Justin Bieber!

TMZ reports that Hailey has already filed to trademark her new name so she can use on merchandise and stop anyone else from doing so.

Bieber and Baldwin are believed to have tied the knot back in September at a New York City courthouse, although they didn't confirm the news themselves until last month verbally to a fan and now to the world on Instagram.

Hailey and Justin have been pretty happy and excited to be husband and wife.
