The 28-year-old says she has decided to go public in order to raise awareness of what intersex means and campaign on behalf of the community.
She is one of the first high profile people to share their intersex status.
Intersex is a broad term which describes a variety of different conditions where internal and external sex organs don't fit typical male and female definitions.
"I have reached a point in my life where I feel ready to share this important part of who I am," Hanne said.
