Pixie Geldof is lending her face to a new campaign to raise awareness of illegal human trafficking. The model has teamed up with Katherine Hamnett to draw attention to this worldwide problem by promoting a slogan t-shirt designed by Hamnett. "Every year 2.5 million people are trafficked globally, and many women my age and younger are forced into the sex trade. It's time we open our eyes to the situation. This is real and it has to stop!" Pixie said.
