The 31-year-old has credited shoes with helping her to become such a successful designer.
Jessica admitted that she loves shoes so much, she even thinks of them as her 'best friends'.
Simpson told US entertainment show Extra: 'Shoes are my best friends, so it's a good thing we have a great relationship. I'd rather have a great pair of high heels than a hug.'
She added that she started her Jessica Simpson Collection after starring on reality show The Newlyweds.
Simpson, who is set to marry NFL player Eric Johnson, said: 'The reason I started the collection was that everyone was wanting to buy what I was wearing on my reality show that I did. I felt like, 'Why am I giving all these other designers props when I could be doing it myself?''
