The 26-year-old Australian supermodel, who is currently working on her new Cozi swimwear range, said that being involved behind the scenes of the fashion industry "diversifies" her life.
Hawkins told OK magazine: "I'm a total control freak when it comes to designing, but I'm really enjoying it. You know, I've got the modelling and television aspect, but designing really diversifies my life. It taps into my creative mind and I think that inspires me."
She said that she turns to her "sister and girlfriends" to test out her designs and enjoys giving boyfriend Jake Wall "a little parade".
