"I am a mother and I am a woman," she said. "I will do whatever I can to raise awareness. I feel very passionate about this."

Victoria then recalled travelling to South Africa this past February where she saw first-hand the devastating effect the disease can have on young children.

"I recently visited South Africa and was so touched by the women I met and felt inspired," she said. "I came home and I knew I had to do something."

After visiting Cape Town and the charity mothers2mothers, an organisation that supports mothers carrying HIV, the fashion designer decided to help donate money and raise awareness of their efforts by auctioning off at least 600 different pieces of her wardrobe.

"It's taken me to get to 40 to realize I have a responsibility as a woman and as a mother," she continued. "For some reason people will listen to me. This is the beginning of an incredible journey for me. I have people mentoring me, I am going back to South Africa in a few weeks and then further afield next year."

David Beckham's wife's desire to help has been driven by the fact that she is a mother of three sons, Brooklyn, Cruz and Romeo, and daughter Harper. "I would do anything for my children and I think every woman has the right to health and every woman has the right to give their children a healthy future," she added.

After her "life changing" journey to South Africa, Victoria now wants to use her high-profile status to start making changes in the world. "I want to get to know the women and understand them. It was life changing when I went to South Africa. Thank you for mentoring me through this," she said. "I have so much to learn, this is just the beginning for me."
