This Friday, Bing is partnering with actress, fashion designer and new mom, Kristin Cavallari, to host the Bing It On Halloween Costume Challenge at the Spirit Halloween store in New York City. Kristin Cavallari is most known as a star of MTV’s Laguna Beach and The Hills. With her wit, charisma and girl next door looks, Kristin has since ventured into movies, fashion and most recently, motherhood.

Cavallari will be challenging New Yorkers to pull together the most outrageous and fun Halloween costume in under five minutes. The winner will receive his or her Halloween costume personally styled by Kristin and her stylist, Tamara Rappa. Those that take the Bing It On Challenge will be eligible to participate in the costume challenge and will also have the chance to win other fun prizes throughout the day. Cavallari will also be trying on various Halloween looks and sharing her favorite Halloween wardrobe and make-up tips during the day.

Kristin will also be hosting this week’s #BingIt chat on Thursday, October 18 from 11-12 PM Pacific. We’ll be discussing Halloween costume tips and tricks and Bing It On via Twitter party. To participate in this week’s #BingIt, follow @Bing and @KristinCav and follow the questions and tweet out your answers with the hashtag #BingIt.
