Hailey touched down in Paris on Saturday, just a day after wishing her husband Justin Bieber happy birthday.

The model has given further insight into her marriage and love for the 25-year-old singer during a new interview with BFF Kendall Jenner.

During the conversation, Hailey admitted she finds it ‘scary to be this young and married’, said Justin, 24, kept her in a ‘weird limbo’ during their on-off romance and admits he is her first serious relationship.

The pals conversed for a Valentine’s special of 23-year-old Kendall’s ZAZA World Radio series on Apple Music’s Beats 1.

Hailey and Justin married in a Manhattan courthouse back in September and she explained more about her love with the pop singer.

The couple have put their plans for a religious wedding ceremony on hold while he focuses on his mental health.

The Canadian hitmaker has been seeking treatment for depression with the support of Hailey and his personal issues are said to have nothing to do with his marriage.

She said: ‘It’s definitely scary to be this young and be married. It’s a scary thing, but it’s also the person that I’ve literally been in love with for so many years.

‘So, that’s the best part about it. Like I feel like he’s my best friend. And we just get to do life together forever, now. But I think the forever aspect for me is just like, you don’t think about that until you get married.

‘And then you’re like, okay, this is really like, this is forever. Meaning like, there is no end.’
