The 21-year-old model - who is the daughter of actor Stephen Baldwin and his wife, graphic designer Kennya - has admitted that her sports shoe collection is "next level" and she has to donate clothes every six months as she is sent so much by Adidas - who she recently launched her first collection with, unveiling it at London Fashion Week with a catwalk show which featured Winnie Harlow and Leomie Anderson.

In an interview with Glamour, she said: "Honestly, I have too many clothes. Adidas spoil me, they send me boxes and boxes of doubles and triples of the same thing. I mean - love them to death - but I have a fitting room at my house and there's sneakers all over the floor. I go through cycles of donating stuff every six months because it's so much. 

"The sneaker collection is next level. I have like 150 pairs. As I have gotten a little older, I have gotten tidier for sure. I at least know how to find everything now. Everything has a place - even if it's not co-ordinated."

The blonde beauty - who is married to pop star Justin Bieber, according to her uncle Alec Baldwin - is known for her signature casual look comprised of sweatshirts, tracksuit bottoms and hoop earrings, and has admitted she likes to keep it simple when styling herself. 

Hailey said: "When it comes to styling tracksuits, I think it's about doing something simple. Like what I am doing! I will wear trackies with a really cool coat, a leather jacket or a cool sweater. What we are doing with a lot of it in the show is putting those cool diamond earrings with everything, or cool sunglasses. Putting on a cool pair of sunglasses can change everything - you can be in an actual gym outfit and you can walk through life not looking like a mess."
