The couple were reported to have tied the knot last month after a short engagement, but it has now been claimed that whilst they are technically married, they don't believe it is official yet because they haven't had a full ceremony in a church.

Both Justin, 24, and Hailey, 21, are religious, and according to TMZ, they think a church ceremony is necessary to make the marriage meaningful in the eyes of God, which is when the marriage will become official.

The 'Sorry' hitmaker and the model reportedly got married on the day they received their marriage license in New York, and it was claimed Justin's friend Josh Mehl was a witness at their wedding ceremony on September 13, which was officiated by preacher Jeffrey Quinn, a member of the faculty at Nyack College, which is near the courthouse in New York City.

The couple are still planning on a formal ceremony, but it will be a wedding in name only as they are already husband and wife.

Hailey previously denied having married Justin on Instagram.

She wrote: "I understand where the speculation is coming from, but I'm not married yet!"

However, days later her uncle Alec Baldwin claimed his niece and the 'Love Yourself' hitmaker had "just went off" and got married.

He said: "They just went off and got married and I don't know what the deal is. We text Hailey every now and then. We met him one time."

Meanwhile, Hailey recently claimed her engagement was the "most adventurous thing" she's ever done.

She said: "My entire summer has been quite adventurous in life in general. I've been traveling all over. For me, being adventurous is flying by the seat of my pants, which isn't something I'm normally comfortable with, but I've been doing it for the last few months. Just traveling, and it's so fun to be able to pick up and do things.

"Well, I got engaged! I think that's probably the biggest OMG moment of the year for me, of my life. So that's probably top."
