My biggest fear is the people I love not knowing how much I love them. I just want to remind people all the time.

I think it's so important to practice what you preach - whether you're into riding cows to work or eating a burger after boxing, just do what you're telling your fans you're doing because you have to be real with them because they look up to you.

I think that not being perfect has given me the freedom to keep getting better.

I get to go back and ride my horses with all the people that I grew up with because that's really fun for me.

I was always in front of the camera. My mom was really passionate about photography - I have pictures of my whole life. I've always just been in front of my mom's camera and it's always comfortable to me.

Bella [Hadid] is also very naturally gifted in beauty so she can also go whenever she wants to go to the gym.

My fitness inspiration has always been athletes, my whole life. Serena Williams is a great friend of mine and Ronda Rousey - we did Sports Illustrated together. Obviously, following powerful women and seeing their bodies and how hard they work is really inspiring to me.
