Lauren Conrad spends the night at the Pur Jeans Halloween Party at STK in West Hollywood, Calif. on Friday night.

The 22-year-old Hills star has just partnered with Campus Solutions, Inc., and TheQuad.com to bolster the awareness of the “Lauren Conrad Collection.” Campus Solutions, Inc. will deploy a small army of its brand ambassadors to each of the schools where they will engage students, distribute branded materials and promote to sorority sisters at their houses and during chapter meetings.

Lauren Conrad will be the spokesperson and featured host of each runway show along the tour.
