As a surprise to many, Victoria Beckham skipped the opening of her first store in London's Dover street to speak in New York for the UN.
Victoria Beckham has been involved in many charities in the past, including Sir Elton John's Aid's foundation. She also recently visited South Africa where she went out to support Born Free, a foundation that focuses on the issue of transmitting HIV from mothers to their children.
When she returned she knew that she had to do something to help raise awareness and money for the cause. The first way to help? Donate a large portion of her wardrobe to net-a-porter to sell online. The money made went to Mothers2Mothers, a non profit organization helping the transference of HIV's to babies.
At the United Nations, Victoria Beckham spoke of her "responsibilities as a woman and a mother" and using her voice to help bring light to this cause. She will work with UNAIDS, the UN's HIV and Aids charity.
Victoria admitted she was still learning and was being mentored along the way, but went on to say, "It's taken me getting to 40 to realise I have a responsibility as a woman and a mother,"
"I recently visited South Africa and was so touched by the women I met. I felt inspired and I came home and knew I had to do something."
