First of all - as you may have guessed from her name, Hailey is a part of the famous Baldwin family. Her dad Stephen is an actor, who has appeared in many movies and TV series - and in recent years on many reality shows including Celebrity Big Brother in 2010.

Hailey and her dad seem to have a good relationship - old-school Justin reportedly asked Stephen's permission before proposing. However, Hailey has spoken out about her distaste for her father's political views - Stephen was a staunch supporter of Donald Trump in the lead-up to his election. In 2017 she told The Times: 'We didn't see eye to eye. It was a very big issue for me, but my dad's still my dad. I would never let politics get in the way of family. It's over now, and his opinions have changed with how everything's now unfolding. Every day, the news freaks me out. It's terrifying.'
Early ambitions
As a member of a famous family, Hailey has been in the spotlight from a young age. She first appeared on TV in a documentary with her family way back in 2005 at the tender age of 9.
However, being a model wasn't always Hailey's plan. Initially she dreamed of being a professional ballet dancer but an injury to her foot meant she had to put this dream aside. She now loves boxing as it reminds her of dance.
She's also not someone who relishes fame too much - she says it's 'not all it's cracked up to be' and she cherishes her alone time, 'watching TV and chilling' by herself.
Famous friends
Despite this, being a model, Hailey hangs round in pretty high-flying circles. She's close friends with all of the Kardashian clan and can often be seen in Instagram snaps with them. She's especially close with Kendall and the pair have matching tattoos on their fingers.
Love
Hailey and Justin first met as awkward teenagers back in 2009 when they were introduced by Hailey's dad Stephen. Since then, their relationship has been through its fair share of ups and downs as they've gone from being 'just friends' to 'dating but not exclusive' then not speaking for a long period of time.
They finally got it back together in May this year and Justin popped the question on holiday in the Bahamas little more than a month later.
We can't wait to see what's next for the young lovers!
