Lauren Conrad made her red carpet debut with boyfriend William Tell on Friday night at the Susan G. Komen foundation's Designs For the Cure gala. The event was hosted by Lauren at LA's Millennium Biltmore Hotel. Lauren seems to be getting more and more comfortable stepping out with William — the duo were also photographed together a week ago at the Veuve Clicquot Polo Classic. Lauren organized Friday's bash as one of many celebrities getting active during Breast Cancer Awareness Month, and the proceedings featured models in some of her Paper Crown designs. The coming week is set to be a busy one for Lauren, too, since she just landed in NYC ready to kick off her latest book tour.
